Their dialogue exchange goes like this.
Cloud: ?Que paso?
Cloud: ?Que hora es?
Cloud: ?Donde esta en la biblioteca?
Basically what most of the dialogue exchange are in this game.
It would bring up some haters, but it would be really cool if they used elements of Twinsanity Crash and had co-op attacks with Cortex, who would have the majority of the speaking role.
At the very least, the Rollerbrawl would be a cool level two. (I'm going to go out on a limb and say that if we ever got Crash his level three would probably be wearing Aku Aku for invincibility, that is, if Activision doesn't make them shoehorn Mutants into this)
