PrettyBalloon is the second boss of Bomberman Tournament. It is the result of Pretty Bomber fusing with Pommy Sea. It switches between three forms when damaged: an octopus form, a jelly form, and a divided form.
PrettyBalloon begins the fight in this form. It moves slowly and aimlessly, maneuvering through the grid and turning upon colliding with obstacles. Occasionally, it will pursue Bomberman. While in this form, PrettyBalloon continuously fires bullets one at a time from the two large tentacles at its sides, alternating between firing from each tentacle. The bullets fly directly at Bomberman, passing over all obstacles, and will harm him on impact.
The octopus form is PrettyBalloon's weakest form. With a single blast from a bomb, it will immediately switch to its jelly form. However, this does not deal the boss any real damage.
While in this form, PrettyBalloon may fire gels multiple times. Each successive time, it will fire from the sides that it hadn't already fired from, creating new vulnerable dents and filling in the previous dents. After some time, it will morph back into its octopus form if it has not been damaged.
DividedDrops. The gels initially fly in each direction in a circle, with each cardinal gel being about four tile spaces from the middle of the split. These gels then proceed to move quickly, randomly changing directions. They are all invincible. Eventually, they will reassemble at some position and the boss will change back into its octopus form.
After taking damage in its jelly form four times, the boss will be destroyed. Upon its destruction, Pommy Sea is returned to Bomberman, and PrettyBomber escapes.
