Squirrels!

There should be squirrels in Minecraft!

The squirrels should spawn in Taiga or Old Growth Taiga biomes and have the ability to run up and down trees. They will run away from players and will sometimes be chased by foxes. Squirrels will dig up nuts from podzol, (a bit like foxes dig up things) and the nuts will look similar to acorns and pinecones. When spruce trees decay, as well as sticks and saplings, the leaves can also drop acorns, pinecones, nuts etc. Squirrels can be bred/tamed with these nuts. Most squirrels will be grey, but like pandas and axolotls, there can be a rare chance a red squirrel will spawn and can be bred to make more red squirrels. Squirrels also don't take fall damage.
