In the first Mumbo Jumbo stage there is a part where Beastboy is holding a bus. Use Starfire to protect him. Use Starfire's super move repeatedly to keep the giant rabbits stunned. If one gets close to Beastboy, use Starfire's charged starbolt attack. In the second Mumbo Jumbo stage, towards the end of the fight there will be a corner of the level with each Titan's face in a circle. Take each Titan one by one to the circle that represents them. They will lock in place until you get all five. Then, a big attack that will defeat Mumbo Jumbo will occur.
