As far as i know, all the floating shanpes can do is fly at you semi-fast semi-slow, and also speak in breakcore. The firey ones explode on death and also shoot projectiles i think, and also speak in breakcore but in a deeper voice. The oopy goopy mass, uh, it just.. teleports? I think? Im pretty sure thats all it does, other than one attack it does occasionally where it rushes at you from the sides and tries to send you to its prison dimension
