Become a squirrel origin with peculiar eating habits in your world.
This origin is a squirrel that doesn't eat all food, but can store some for later.

Its helpful powers are:
Climbing
You are able to climb any wall, not just ladders. [Toggleable with Origins primary key].
Cheek-Pouches
You have large cheeks to store more food when foraging. Any item that is not food is dropped on death. [Access With Secondary].
Acrobatics
You never take fall damage, no matter from which height you fall.
Strong Ankles
You are able to jump higher while sprinting.
Neutral features are:
Plains Spawn
As a squirrel you will always spawn in a plains biome.
Smol
You're a tiny squirrel, even smaller than a block.

The less helpful features are:
Squirrel Diet
As a squirrel you can only eat walnuts and other squirrel food.
3 Hearts
As a creature of small size you only have 3 hearts, use them wisely!
Large Appetite
You exhaust much quicker than others, thus requiring you to eat more.
Unwieldy
The way your hands are formed provide no way of holding a shield upright.
Timid Nature
You deal less damage in combat. Squirrels aren't warriors...
