Shaped like a beetle, the Kanabuns have round black bodies with a red helmet-like upper shell, a pair of black eyes, and a pair of blue antennas. On their rear they have four ovular light blue wings which they use to fly in a similar fashion to a propeller.
In gameplay, the Kanabuns fly in and out of the background and foreground in spiral patterns in an attempt to damage the playable character. The playable character can only make physical contact with them when they are on the same plane as the playable character however. Otherwise, the Spin Jump can easily defeat them in mid-air.
In the Bad Future or sometimes in the present timeframe of the Rounds, the Kanabuns have decayed; their upper shell has turned purple, their sclera have turned green, and their wings are holed. These dilapidated variants fly even slower than before, making it even less of a threat. Also, like every Badnik in the game, the Kanabuns are powered by Little Planet flower seeds which will pop out of them after they are defeated.
- Kanabun (カナブン?) is the Japanese word for beetle.
