Boomer

Boomer is the third boss from Toki: Going Ape Spit.

Details
Boomer is a giant submarine piloted by various Geeshergams and with a Geeshergam face in the front, much like the Big Geeks found in the first area of the stage. It will move up and down while shooting torpedoes which also have Geeshergam faces on them and can be destroyed, eventually stopping to dash forward at the player during which time it's invulnerable.
