Can't have Killer Klowns without Klownzilla. I get that he can't be a playable character, but how about a level boss or trap? where the klowns have to feed him enough cotton candy before time runs out, or he will attack and kill them. and the humans have to feed him poison. which ever team fed him the required amount of cotton candy or poison wins, and decides which team he kills.

I have an idea. Klownzilla Boss Mode. (You can get cool cosmetics from defeating the boss) Klownzilla will shoot out cotton candy balls that you have to throw back at him, while henchmen-klowns are coming out of pipes. Klownzilla can also slam the ground, which is when you have to stand on platforms around the boss arena to avoid taking damage. When Klownzilla slams the ground the henchmen-klowns are more vulerable to attacks. Klownzilla can also grab a klown and throw it at you. The klown would be damaged if Klownzilla missed, so you can throw the cotton candy balls at the klown, making them immobile. Once you throw 30 cotton candy balls at Klownzilla, the cotton candy is so sticky, it traps him, which you can then shoot his nose. (Weapons spawn around the boss arena too)
