Sounds quite logic to me. It is actually strange that the brown mooshroom was not directly implemented with the red guy. Maybe because red mushrooms are more rare in the game. Some texture packs have already painted brown mooshrooms, but the mushrooms they give are of course still red.
Indeed, When they added the Red Mooshroom, the should of added a brown one too
Appearance: The Same as a Red Mooshroom but Brown Instead of red!
