Donkochu

This young stage of a donchu. Though it cutely rolls around, given the fact that it would grow up to become the "destroyer of forests," it is quite ferocious. They travel alongside their guardian donchu, preying on both flora and fauna in every forest they go through. Donchus not only gravely affect the ecosystem of the land, but they also attack humans that come close to them, so it's best to exterminate donkochus before things get out of hand.
