Bobo

Bobo is a boss in Wario Land II and appears as a large bird-like monster that is apparently kept as a pet by the Black Sugar Pirates. When faced in battle Bobo dives at Wario with his powerful talons and also whips up a powerful gust of wind with his wings that lifts Wario off the ground temporarily. Bobo will turn bright red when his health reaches a critical low, at which point two hits are sufficient to fell the bird - whose ultimate fate is unknown as he falls off the screen.
