Yeah, I like that idea, he could really spice things up in the heat of battle!!
Alright, here's Mr. Randoms side special, the bucktooth bazooka. Mr. Randoms fires his bucktooth out of his mouth like a missile. While the missile is fired, Mr. Randoms will be stuck in place until the missile hits somebody or it travels a certain distance and falls (and when it hits the ground, it'll disappear, perhaps it could be use as an item that somebody can pick up when it reaches the ground?). The bucktooth could transform into a missile, or it could stay the same, so I made two versions and made a transformation from bucktooth to missile. When the missile hits somebody, it'll explode with a little message, like boom, LOL, or a Mr. Randoms design (this could be used for the random bomb as well). The explosion could last for one loop, which is just 3 frames of animation (would more be needed, or is that alright). Mr. Randoms head is supposed to be crazy and random looking, even the part where his head disconnects with his body (fits his nature, cause it's his name, even the Mr. part :0), made it based on Pac-Man a little bit.
