Bomberbirds are the main monsters appearing in the Minefield. When the player has few treasures, these monsters do not spawn commonly; however, if the player collects some Bomberbird Eggs and retracts to a place with uncollected eggs, those eggs may hatch and spawn Bomberbirds. Starting at 21 eggs, the Bomberbirds will start spawning randomly.
Bomberbirds are flying creatures. When killed over a mine, the mine is detonated; when killed over other land, the Bomberbird will drop a mine.
