Online game

Plankton's Pernicious Plot is a SpongeBob SquarePants online game.


Plankton has hypnotized the jellyfish at Jellyfish Fields. SpongeBob must de-hypnotize the jellyfish by jumping on the hypno-pods. Jumping on a hypno-pod de-hypnotizes all nearby jellyfish. Hypnotized jellyfish will sting SpongeBob, but SpongeBob can pick up de-hypnotized jellyfish for points. If a hypnotized jellyfish stings SpongeBob, he will lose some health. If he loses all his health he loses a life. There is also a timer and the level must be completed before the time runs out or SpongeBob loses a life. There are also power-ups. The squarepants give SpongeBob an extra life, the Krabby Patty gives SpongeBob more health and the stopwatch gives SpongeBob more time. If SpongeBob loses all his lives the game ends.
