This is a very fun game by the way. It has everything from a police robot, controlled by a dog and some guy that looks like Wario, a Totoro-esque giant bunny, among other things.
From Wikipedia:
"Being a clear parody, Bonus Kun's attacks and moves are direct adaptations of Ryu's, including a version for each of his attacks such as Bonus Kun's Kou Shuu Tan, which parodies the popular Hadouken. His victory poses mimic those of Ryu's. Like Ryu he turns while his headband blows in the wind and his smile is similar to Ryu's smile and raised arm victory pose. Due to lack of limbs, he cannot crouch, block, or grab opponents."
