SpongeBob is trying reach the surface of the ocean so he grab the stolen Krabby Pattyformula. In order to the surface, SpongeBob must go up by using a fan. To activate the fan, press the space bar. Letting go of the space bar stops the fan. While going up, be sure to avoid jellyfish and floating wood. Touching the wood or jellyfish causes SpongeBob to get hurt and ends the game. If you see a Krabby Patty, grab it to score extra points. On the left side of the screen, there is a meter. The meter tells on how far SpongeBob is from the surface. The meter rises when the player goes up and the meter decreases when the player goes down. The game ends when either SpongeBob gets hurt or he reaches the surface and retrieves the stolen Krabby Patty formula.
