I'd like to propose the addition of ferrets to Minecraft. Some miscellaneous attributes for them would be...
- They would live in the desert, savanna, and snowy biomes like snowy tundra and snowy taiga.
- They can burrow underneath grass, sand, dirt, or snow by two blocks, and cause the bottom block in the hole to become podzol.
- They would be bred and tamed by raw or cooked fish (and maybe some other meats).
- They could act as an 'advanced' version of cats, that actually attack creepers; it would be the first mob to do so.
- They could drop ferret hide, which would act just like rabbit hide; craftable into leather.
- They could ride on a player's shoulder, just like a parrot.
I'm not able to really think of anything else. Outside of a mod (Animania), I've never seen ferrets for minecraft suggested or talked about by anyone. The mod in question has an image for ferrets, so I'll put that here:
