Instructions
Choose Ben's spider monkey form when the fight begins. The speed of this form will prove to be useful.
Dodge the boss range attack, which involves spraying smoothie out of his straw. After the spraying, quickly move in and hit him.
Quickly move away after hitting him so as to avoid his physical attacks, which include punching and stomping. Other than his physical attacks, the ranged attack with the straw make up his entire move set.
