"Bet you can't do THIS!"
The young Skater practices all the time to be the greatest skateboarder in the world. He lives for speed and tricky stunts, and when he's around, any and every surface becomes his own private skate park. His board is his prize possession, and he always makes sure to keep it clean and shiny, even when he gets totally grungy himself.
The Skater is extremely competitive, and he can't stand to see anyone do something better or faster than he does. His rivalry isn't just limited to other skateboarders - he'll try to out-race trains and out-jump pigeons flying in the park, just to prove he can. He hasn't beaten them yet, but he's sure he will some day!
