Overview#
Rat’s Mischief is a Vanilla+ styled mod for Fabric that introduces rats—versatile mobs that can be tamed to serve as loyal pets or efficient workers. Unlike other mods that focus on complex machinery, Rat's Mischief emphasizes a 'summoner' approach, allowing players to manage a 'mischief' (a group of rats) to perform tasks like harvesting, breeding animals, and defending their owner.




Rats are designed to feel integrated into the base game, featuring unique behaviors such as item collection, potion consumption, and immunity to environmental hazards like cacti and berry bushes.
Rats#
Spawning
Rats do not spawn in the wild like typical animals. Instead, they appear in previously inhabited villages that have become abandoned.
- Conditions: A village must have no remaining villagers but must still contain beds.
- Group Size: They spawn in small groups of up to 5 if a player is nearby.
- Structure Note: This mechanic only applies to villages that were once normal and became empty; it does not apply to the default 'Abandoned/Zombie Village' structures generated at world creation.
Stats and Combat
Rats behave similarly to wolves, attacking targets that the player strikes or those that harm the player.
| Stat | Value |
|---|---|
| Health | 8 Points (4 Hearts) |
| Attack Damage | 1 Point |
| Fall Damage | Starts at 15 blocks |
| Special Combat | Ignores invulnerability ticks |
| Environmental | Immune to Cacti and Berry Bushes |
| Oxygen | Breathes 5x longer than players |
Because rats ignore invulnerability ticks, a large group (mischief) can deal massive DPS by hitting a target simultaneously without being blocked by the standard damage cooldown.
Taming and Behavior
Rats can be tamed using any food item. The higher the saturation/quality of the food, the higher the chance of successful taming. Once tamed, they can be ordered to sit or follow.
- Cat Distraction: If a following rat sees a cat, it will temporarily stop following to chase the cat away.
- Item Collection: Rats automatically pick up item stacks on the floor. Tamed rats will bring these items back to their owner.
- Self-Healing: If a rat is injured and holding food, it will consume it to restore health (based on the food's saturation) and gain any associated status effects.
- Potion Consumption: Rats will drink any potion they find on the ground. They convert saturation into a Regeneration effect and gain the potion's standard effects.
Rat Types#
Rats come in various visual variants categorized by how they are obtained.
Natural Variants
These are the only types found spawning in abandoned villages.
- Wild Rat: The standard appearance.
- Golden Rat: A rare variant with a 1 in 150 (0.66%) spawn chance.
Pet Variants
Obtained by breeding two wild rats. Their offspring will randomly be one of the following seven types:
- Albino, Grey, Husky, Russian Blue, Light Brown, Chocolate, Black.
Special Named Variants
Renaming a rat with a Name Tag to specific names will change its appearance. These variants often feature custom textures for Elytrats as well.
| Name | Reference/Origin |
|---|---|
| doctor4t | Mod Creator |
| Arathain | Texture Artist |
| Astron / Astronyu | Artist |
| Remy | Ratatouille (Requires the rat to be a Russian Blue type) |
| Ratater | Botania |
| Jorato | JoJo’s Bizarre Adventure |
| Hollow Rat | Hollow Knight |
| Jerma | Jerma's Rat Movie |
| Biggie Cheese | Barnyard |
| Rateline | Madeline (Celeste) |
| Rat Kid | A Hat in Time (Can be dyed 16 colors like sheep) |

Equipment and Items#
Elytrats
An Elytrat is a special item that allows rats to fly.
- Equipping: Shift-use a rat with an Elytrat item, or let a rat pick one up from the floor. To remove it, shift-use the rat with a bare hand.
- Behavior: Elytrats will fly to follow players through the air and will dive-bomb enemies during combat.
Rat Pouches
Pouches are used to store and transport rats. Stored rats do not age and retain all health, names, and status effects.
- Usage: Use on a rat to pick it up. Shift-use an empty pouch to gather all rats in a 16-block radius. Shift-use a filled pouch to release all rats.
| Pouch Type | Capacity | Crafting Material |
|---|---|---|
| Leather Pouch | 5 Rats | Leather |
| Twisted Pouch | 10 Rats | Twisted Vines |
| Chorus Pouch | 20 Rats | Popped Chorus Fruit |
Staves
Staves cannot be crafted. They have a 5% chance to be held by a rat when it spawns in a village or is born. Taming the rat allows the player to take the staff. Using a staff issues a 15-second order to nearby rats.
- Harvest Staff: Rats harvest mature crops and replant seeds. If they have Bone Meal, they will fertilize crops.
- Love Staff: Rats will breed nearby animals (and themselves) if the appropriate food is available on the ground.
- Collection Staff: Use on a block to make rats mine that specific material. They can break blocks with a hardness of 1 (increased by +1 per level of Strength). Haste increases mining speed by 20% per level.
Mask of Rat
A rare headgear item with unique properties.
- Acquisition: Purchased from Wandering Traders (40 Emeralds), a 0.5% chance from breeding baby rats, or by killing the player 'doctor4t' on a server.
- Properties: Provides 1 armor bar and has high gold-tier enchantability. Repaired with Phantom Membranes.
- Effect: The wearer cannot hurt rats. All status effects (Invisibility, Strength, etc.) and enchantments on the mask are shared with all of the wearer's tamed rats.

Recipes#
Most items in Rat's Mischief follow a 'Bundle-like' crafting pattern.
| Item | Recipe Components |
|---|---|
| Elytrat | 2x Phantom Membrane + 1x Leather |
| Leather Pouch | 6x Leather + 2x String |
| Twisted Pouch | 6x Twisted Vines + 2x String |
| Chorus Pouch | 6x Popped Chorus Fruit + 2x String |
Note: Staves and the Mask of Rat are uncraftable.

Special Events#
The mod features several hard-coded calendar events that change rat behavior and appearance.
- World Rat Day (April 4th): All rats perform a 'smug dance.' Golden Rat spawn rates increase from 1/150 to 1/30.
- RAT’s Birthday (July 19th): For one week, rats wear party hats and smug dance. Adult rats have a 20% chance to spawn holding a Cake. Wild rats have a 10% chance to spawn as the 'doctor4t' type.
- Mod Anniversary (December 28th): For one week, rats wear randomized party hats and smug dance. Wild adult rats have a 20% chance to be a completely random type (including special/named types) and a 20% chance to spawn holding a Cake.
