As of right now, there are not very many uses for the monkey greegrees that you can get after completing Monkey Madness. So I suggest that Jagex should add an Arena on Ape Atoll where we can fight each other as monkeys. It would be like the Fight Pits, except that when you win you get tickets that you can trade in for stuff. Some stuff you would be able to get would be new Monkey Greegrees, the ability to use greegrees anywhere, and weapons and armor that you can equip while you're in monkey form. Anybody else like it or have some suggestions? :)
