Bronto Burts are pink spherical enemies with small wings they use to fly and orange feet. They usually come in groups of three to five and attack in flocks, usually in a formation such as a zigzag or a vertical line. Some Bronto Burts will chase after Kirby and try to run into him, and some just take off and fly away very fast when Kirby gets near. Some stand on ground and then attack or fly straight ahead when Kirby comes too close. Just like Waddle Dee is the most common enemy on the ground, Bronto Burt is the most common enemy in the air. Also like Waddle Dee, Bronto Burt does not give Kirby a Copy Ability when inhaled.
Bronto Burts were previously set to make an appearance in an unnamed Kirby level in Adventure mode. Other than their appearance in the aforementioned game mode, nothing was revealed about their behavior.
