Kirby: Right Back At Ya!
Baton Twirling Kirby (Baton Kirby in the dub) only appears in anime, Kirby: Right Back at Ya!. He wears a cloth on his head with a little star-tipped baton design on it. The baton he wields is red and yellow, with mini-figures of himself on the ends. With it he zaps the enemy with a yellow beam and controls them. If he twirls his baton, the enemy is spun around as well. If Kirby throws his baton, the baton and the enemy explode.
The sequence starts with a twirling baton. Kirby grabs it, twirls it, and strikes a pose.
