Belly Bounce is a SpongeBob SquarePants online game.
It was released in 2009 to celebrate SpongeBob's 10th anniversary.
In this game, SpongeBob bounces on Patrick's belly. The player controls Patrick by moving the mouse left and right and must keep SpongeBob above the water by bouncing him up when he falls. Every bounce earns the player one point. Falling Krabby Patties can be collected by both SpongeBob and Patrick. They are worth one point each. There are also falling pink and blue jellyfish that the player must avoid. If Patrick is stung by a jellyfish, he is rendered immovable for a very short time and the player loses a life. Letting SpongeBob fall into the water also takes away a life. When the player loses all three lives, the player loses and thus the game ends.
