Buzzbomb

A Buzzbomb is an enemy found in Bubblegloop Swamp, the Autumn season of Click Clock Wood, and certain areas of Gruntilda's Lair. Resembling a yellow dragonfly-like creature, it flies around in the air and swoops down to attack Banjo and Kazooie. Once noticed, it is a relatively weak enemy that can easily be dispatched with Kazooie's Rat-a-tat Rap ability.

Trivia

 * In the N64 version of Banjo-Kazooie, a Buzzbomb appears in the opening scene shortly after the game is turned on. It will fly around the screen making a buzzing sound before crashing into a Rareware logo and falling into a pond below.
 * The Buzzbomb looks exactly like Sparx from the Spyro the Dragon series.
