Autumnity Mod Guide: Maple Forests, Snails & Seasonal Content
Autumnity brings the beauty of autumn to Minecraft with vibrant Maple Forest biomes, colorful falling leaves, and a charming new mob: the Snail. Beyond aesthetics, the mod adds a full Maple wood set, a Sap-to-Syrup food chain, craftable Snail Shell armor with unique defensive abilities, and a new Sturdiness potion for knockback resistance.
Overview
Autumnity is an atmosphere-focused mod that adds autumn-themed biomes, blocks, items, and a new passive mob to Minecraft. The centerpiece is the Maple Forest biome, filled with Maple Trees in four stunning leaf colors: green, yellow, orange, and red. Colored leaves produce falling leaf particles, creating one of the most visually immersive biome experiences available.
Beyond the scenery, the mod introduces a complete Maple wood building set, a Sap harvesting system that produces drinkable Syrup, and the Snail, a peaceful creature that eats Mushrooms and leaves trails of Slime. Snail drops can be crafted into unique armor and brewed into potions. You can browse every item and recipe the mod adds using the tabs on this page.
Getting Started with Autumnity
- 1
Find a Maple Forest
Maple Forests generate naturally in cool biome regions. Look for dense forests with brightly colored leaves in red, orange, and yellow alongside standard green
Maple Leaves. The biome has a temperature of 0.7 and spawns common Overworld animals alongside Snails. Maple Trees can also appear in regular Forests, Wooded Hills, and Flower Forests, though less frequently. - 2
Harvest Maple Wood
Chop down Maple Trees to collect Maple Logs. These work exactly like vanilla wood types and can be crafted into a full set of building blocks: Planks, Stairs, Slabs, Fences, Fence Gates, Doors, Trapdoors, Pressure Plates, and Buttons. Collect the colorful leaves and saplings too, as all four leaf colors have their own saplings for replanting.
- 3
Collect Sap from Maple Logs
Use an Axe on a Maple Log or Maple Wood block. There is a 25% chance it will transform into a Sappy Maple Log instead of the usual Stripped variant. Once you have a Sappy log, right-click it with a Glass Bottle to collect a
Sap Bottle. The Sappy log reverts to a Stripped Maple Log after harvesting, so you will need to find more Maple Logs to repeat the process. - 4
Befriend a Snail
Snails spawn naturally in Maple Forest biomes. They are passive but will hide in their shells if you get too close or sprint near them. Approach slowly while sneaking to avoid startling them. You can feed adult Snails mushrooms (Brown Mushrooms, Red Mushrooms, Mushroom Stems, or Mushroom Blocks) to make them produce
Snail Slime, and breed them using Mushroom Stew or Suspicious Stew. - 5
Collect Snail Shell Pieces
When adult Snails die, they drop Snail Shell Pieces. These are the key crafting material for the
Snail Shell Chestplate and are also used to repair it. You do not need to kill Snails to progress with the mod, but the shell pieces unlock the mod's unique armor and are worth collecting over time.
Maple Trees and Wood
Maple Trees are the defining feature of Autumnity. They generate in four leaf variants: standard green Maple Leaves (which use biome-tinted foliage colors like vanilla trees), 
Yellow Maple Leaves, 
Orange Maple Leaves, and 
Red Maple Leaves. The colored variants produce beautiful falling leaf particles, making Maple Forests one of the most visually striking biomes in modded Minecraft.
Each leaf color has a corresponding Sapling, so you can grow any color of Maple Tree anywhere you like. All four leaf types and saplings work in Composters with a 30% chance to raise the compost level. The leaves are flammable, so be careful with Lava and Flint and Steel near your decorative builds.
Maple Wood Building Set
Maple wood has a warm, honey-toned color that sits between Oak and Birch. The full block set includes 
Maple Planks, Maple Stairs, Maple Slab, 
Maple Fence, 
Maple Fence Gate, 
Maple Door, 
Maple Trapdoor, 
Maple Pressure Plate, 
Maple Button, and a 
Maple Boat. Maple Logs can be stripped with an Axe just like any other wood type. All wooden blocks are flammable and have standard wood hardness values (2.0 hardness, 3.0 blast resistance for planks).
Leaf Carpets
Yellow, Orange, and Red Maple Leaves can be crafted into Leaf Carpets. These are thin decorative blocks (only 1 pixel tall) that sit on top of surfaces like regular Carpets but with a leafy texture. They are perfect for creating forest floor decorations, garden paths, or seasonal builds. Leaf Carpets have no collision, so entities pass through them freely.
If you have Quark installed, Autumnity automatically adds Maple Vertical Slabs, 
Vertical Maple Planks, a Maple Bookshelf (provides enchanting power just like vanilla Bookshelves), a 
Maple Ladder, and a green 
Maple Leaf Carpet. These blocks register only when Quark is detected, so they will not appear in your creative menu without it.
Sap and Syrup
Autumnity introduces a simple but satisfying Sap harvesting mechanic. When you use an Axe on a Maple Log or Maple Wood block, there is a 25% chance the block becomes a Sappy variant instead of the normal Stripped variant. The Sappy Maple Log (or Sappy Maple Wood) visually drips with sap and can be harvested by right-clicking it with a Glass Bottle, which yields a Sap Bottle and converts the block into its stripped form.
Sap Bottles can be smelted into Syrup Bottles, which are a food item that restores 4 hunger points and 0.3 saturation. Like Honey Bottles, drinking a 
Syrup Bottle returns a Glass Bottle. Syrup Bottles stack up to 16, making them a decent portable food source in the early game. They are especially handy if you have built a Maple tree farm, since you can produce Sap passively while collecting wood.
The 25% Sappy Log chance triggers each time you right-click a Maple Log with an Axe, and it damages the Axe by 1 durability regardless of whether the sappy variant appears. Plan to strip a large number of logs at once to get a good supply of Sap Bottles.
The Snail
The Snail is Autumnity's signature mob, a slow, peaceful creature that spawns in Maple Forest biomes in groups of 2 to 3. It has 18 health points (9 hearts), 1.0 attack damage, and moves at a speed of 0.25. Despite its sluggish pace, the Snail has several unique behaviors that make it one of the more interesting passive mobs in modded Minecraft.
Hiding Behavior
When any living entity (except other Snails) comes within 0.3 blocks, the Snail retreats into its shell. While hiding, it cannot move, eat, or look around, but it gains a massive +20 armor bonus, making it extremely tough to damage. The Snail will also hide immediately when taking damage, spitting out any food it was eating. It has a 1% chance per tick to emerge from its shell on its own, but only when no threats are nearby. Approach Snails by sneaking or in spectator mode to avoid triggering this behavior.
Feeding and Slime Production
Adult Snails can be hand-fed mushroom items: Brown Mushrooms, Red Mushrooms, Mushroom Stems, Brown Mushroom Blocks, and Red Mushroom Blocks. With Quark installed, Glowshrooms and Glowshroom Blocks also work. When a Snail eats a mushroom, it takes 192 ticks (about 9.6 seconds) to finish eating and then produces 5 to 7 Snail Slime blocks on the ground as it walks. Snails can only eat when they are not hiding, not already eating, and have no remaining slime to deposit.
Snails also have autonomous mushroom-eating behavior. If mob griefing is enabled, they will seek out and consume mushroom blocks placed in the world (Brown Mushroom, Red Mushroom, and Quark's Glowshroom blocks). They eat the block directly, destroying it and beginning their eating animation.
Breeding
Snails breed with Mushroom Stew or Suspicious Stew. Simply right-click two adult Snails with either item to trigger the love mode. Baby Snails can be fed these items to accelerate their growth by 10% of the remaining time.
Drops
Adult Snails drop 1 
Snail Shell Piece on death (when mob loot game rule is enabled). Baby Snails do not drop anything. Snail Shell Pieces are the crafting ingredient for the Snail Shell Chestplate and serve as the repair material for it on an Anvil.

| Breeding Items | Mushroom Stew, Suspicious Stew |
| Spawn Group Size | 2-3 |
Snail Slime Blocks
Snails leave behind Snail Slime as they walk after eating. This thin, translucent block is only 2 pixels tall and slows down any entity that walks through it (except Snails themselves), reducing movement speed to 40% of normal. Snail Slime requires a solid surface below it to stay placed and breaks if its support is removed.
Snail Slime Block (Full)
Snail Slime can be compacted into a full 
Snail Slime Block. This block has several interesting properties depending on its surroundings. In its default dry state, it acts as a sticky block (like a Slime Block) and can be used with Pistons. It also has a unique collision shape that is slightly smaller than a full block (1 pixel inset on top and bottom), which allows entities to partially sink into it and negates all fall damage for entities that are not sneaking.
When placed adjacent to Water or Blue Ice, the Snail Slime Block becomes slippery (0.98 slipperiness, higher than regular Ice at 0.989). In this state, it loses its sticky property and gains a full collision box, making it function like a super-slippery surface. This dual behavior makes it useful for both Piston contraptions and ice boat tracks.
Snail Slime Blocks in their dry (sticky) state work with Pistons like vanilla Slime Blocks. Be careful when placing them near Water sources in Redstone builds, because contact with Water changes the block to its slippery state, which disables the sticky property and could break your contraption.
Snail Shell Chestplate
The Snail Shell Chestplate is Autumnity's signature equipment piece. It provides 5 armor points with 375 durability and 9 enchantability. For comparison, an Iron Chestplate has 6 armor points and 240 durability, so the Snail Shell version trades slightly less protection for significantly more durability.
The chestplate has a unique passive ability: while sneaking, it grants Resistance III and the Sturdiness effect. Resistance III reduces all incoming damage by 60%, and Sturdiness provides complete knockback immunity. These effects refresh every tick while sneaking, so they remain active for as long as you hold the sneak key. This makes the Snail Shell Chestplate incredibly powerful for holding your ground against enemies that deal heavy knockback, like Iron Golems or Ravagers.
The chestplate is repaired on an Anvil using Snail Shell Pieces, the same material it is crafted from. Its 9 enchantability is comparable to Iron (also 9), so it accepts standard armor enchantments at a reasonable rate.
Chestplate Comparison
| Snail Shell | Iron | Diamond | |
|---|---|---|---|
| Armor Points | 5 | 6 | 8 |
| Durability | 375 | 240 | 528 |
| Enchantability | 9 | 9 | 10 |
| Toughness | 0.0 | 0.0 | 2.0 |
| Special Effect | Resistance III + Sturdiness while sneaking | None | None |
Sturdiness Effect and Potions
Autumnity adds a new potion effect called Sturdiness, which grants complete knockback resistance. This is the same effect that the Snail Shell Chestplate provides while sneaking, but as a potion it is always active regardless of your stance. The effect also has a special interaction with Iron Golems: when hit by an Iron Golem while under the Sturdiness effect, the upward launch that normally accompanies their attack is counteracted.
The Potion of Sturdiness is brewed by adding Snail Slime (the item form) to an Awkward Potion in a Brewing Stand. The base potion lasts 3 minutes (3600 ticks). Adding Redstone Dust creates a Long Potion of Sturdiness that lasts 8 minutes (9600 ticks). This makes Snail Slime a valuable brewing ingredient, and a good reason to keep a Snail farm running.

Configuration Options
Autumnity provides a config file with several useful options for customizing the mod's behavior. All settings are in the common config.
The Maple Tree Biomes setting controls which biomes Maple Trees generate in outside of Maple Forests. By default, this includes Forest, Wooded Hills, and Flower Forest. You can add or remove biomes from this list to spread or restrict Maple Trees.
The Snail Spawn Biomes setting lets you add additional biomes where Snails can spawn beyond Maple Forests. By default, this list is empty.
The Snail Breeding Items list defaults to Mushroom Stew and Suspicious Stew. The Snail Food and Snail Block Food lists control which items and blocks Snails will eat for slime production. These can be customized to include items from other mods.
Cross-Mod Compatibility
Autumnity has built-in compatibility with several mods from the same team. Quark adds the most extra content, including Maple Vertical Slabs, Vertical Planks, a Maple Bookshelf (functions as an enchanting power source), a Maple Ladder, green Maple Leaf Carpets, and support for Glowshrooms as Snail food. Berry Good, Boatload, and Buzzier Bees also have cross-compatibility features. Having any of these installed alongside Autumnity enhances the experience.
Frequently Asked Questions
Where do Maple Forests spawn?
Maple Forests generate as a cool-type biome in the Overworld with a weight of 8, making them reasonably common. They appear in temperate regions alongside other forest biomes. Individual Maple Trees also spawn in regular Forests, Wooded Hills, and Flower Forests.
How do I get Snail Slime?
Feed an adult Snail any mushroom item (Brown Mushroom, Red Mushroom, Mushroom Stem, or Mushroom Blocks). After eating, the Snail will deposit 5-7 Snail Slime blocks on the ground as it walks. You can also let Snails eat mushroom blocks placed in the world if mob griefing is enabled.
Why does my Snail keep hiding in its shell?
Snails retreat into their shell when any non-Snail living entity gets within 0.3 blocks (about touching distance). They also hide when taking damage. To interact without triggering this, approach slowly while sneaking, or wait for the Snail to emerge on its own (1% chance per tick). Players who are sneaking, invisible, or in spectator mode do not trigger the hiding behavior.
How do I get Sap Bottles?
Use an Axe on a Maple Log or Maple Wood block. There is a 25% chance it becomes a Sappy variant instead of being stripped. Then right-click the Sappy log with a Glass Bottle to collect a Sap Bottle. The log becomes a Stripped Maple Log after collection.
Is the Snail Shell Chestplate better than Iron?
The Snail Shell Chestplate has 5 armor points (vs Iron's 6) and 375 durability (vs Iron's 240). While it offers slightly less raw protection, its sneaking ability grants Resistance III (60% damage reduction) and complete knockback immunity, making it situationally much stronger than Iron in combat scenarios where you can afford to crouch.
Does the Snail Slime Block work with Pistons?
Yes, but only in its dry state. When a Snail Slime Block is not touching Water or Blue Ice, it functions as a sticky block similar to a vanilla Slime Block. If it touches Water or Blue Ice, it becomes slippery and loses the sticky property. Keep this in mind when designing Piston contraptions.
