Buzz-Bomb

From the Super Mario Wiki

A Buzz-Bomb is a combination of a Bob-omb and a Buzzy Beetle (possibly meant to be a Para-Beetle) that appears in the Nintendo Adventure Book Monster Mix-Up. The Buzz-Bomb was created by Bowser and his Monster Mixer, and resembles a regular Bob-omb, though it has a small set of wings sprouting from its back. This allows it to fly somewhat haphazardly.

Like a Bob-omb, a Buzz-Bomb will explode after some time; the Buzz-Bomb's explosion seems more volatile than that of regular Bob-ombs, as it is mentioned that a Buzz-Bomb's explosion obliterated at least forty-seven other creatures.
