Bobo is a giant bird and the guard of the ship belonging to the Black Sugar Gang. He appears as the fifth and second boss in Wario Land: Super Mario Land 3 and Wario Land II, respectively. In both games, he is the boss of the SS Tea Cup stage.
Wario Land: Super Mario Land 3
In the original Wario Land, Bobo attempts to hurt Wario by releasing Watches from his mouth or using his giant, clawed feet and jagged beak. To defeat him, Wario has to use the Watches to propel himself high enough to be able to jump on Bobo's head. It takes three jumps to defeat him. Alternatively, Wario can use the Dragon Pot power to blast Bobo's head or pick up fallen Watches and throw them at Bobo's head three times.
Wario Land II
In Wario Land II, Bobo is considerably smaller than in his original appearance. He only attacks Wario directly in this game by repeatedly swooping down and flying back up again in patterns that change as the battle progresses. Bobo is also able to make wind come up from the ground by flapping his wings, making Wario fly upwards and forcing him back to an earlier section of the boss level unless he crouches. He can be defeated by jumping on him six times or Ground Pounding him three times. Every two hits (or one hit with a Ground Pound), his attack pattern changes. First it is a large and slow curve, then it's in the shape of a w, and finally it is in three lines with 90 degree sharp turns. In addition, every attack pattern transition forces Wario to stay crouched longer.
