You fix a new setting to the ray gun, then fire at the girl. A beam of multi colored light hits the girl and she is knocked to the ground.
Her skin quickly turns pink, and some white patches around her mouth and eyes form. Her nose turns blue and pops into a ball, and her hair turns red, exploding into a large red afro. Her feet grow bigger, snapping her shoes, and her breasts and butt expand, ruining her clothes. They quickly reform as a poofy rainbow striped dress, and her shoes become large green Mary janes.
The new clown stood up, giggled, brushed off her dress, then pulled out some bowling pins and began to juggle them.
"Perfect" you say, while your friends laugh.
