From WiKirby, your independent source of Kirby knowledge.
Benny is an enemy exclusively found in Kirby's Dream Land, appearing in the Extra Game version of Bubbly Clouds - replacing Dizzy - and behaving in much the same way.
Benny resembles a vaguely humanoid figure with stubby handless arms and no visible legs or feet. It bears a blue robe with a blue fez-like hat and a red bowtie. Its round face consists of blank slits for eyes and a tiny line for a mouth. In-game it is typically portrayed bunched-up with its arms raised to its head, and tends to keep this pose at all times.
Benny can be seen tumbling through the sky in straight lines, and moves with alarming speed. It will also rebound along walls. Despite this speed, it can easily be inhaled. Unlike Dizzy, Benny deals two points of damage on collision instead of just one. Benny is worth 400 points when defeated.
