New mob

I propose adding a new mob: the Hedgehog.
It will appear only in Dappled Forest. Its mechanics are such that it will carry apples and mushrooms on its back, similar to fly agarics. It can be tamed by feeding it chicken eggs (MILK IS HARMFUL FOR ADULT HEDGEHOGS!) or carrots. It will reproduce by feeding apples. Every 15 minutes, it will find and give gifts of an apple or mushroom, but there's also a 10% chance it will mistake an emerald for an apple.
