One of Kirby's Copy abilities. This one is unique to the anime, and has so far not appeared in any game.

Along with Water, Iron and Baton Twirling, they all appeared in episode 097 of the show, and were all created by fans! There was a contest in Japan to submit your own Copy Ability ideas, and this was one of the lucky winners.

Top Kirby wears a simple yellow and white cap with a picture of a top. He can send out dozens of spinning tops with star designs on them, that can slice up anything they touch and then explode.
