Role in games
SpongeBob and Patrick control Sandy's submarine and go down Squidward's throat. The player moves the submarine by moving the cursor. Clicking on the mouse button shoots a projectile. Shooting at bubbles scores points.
Collecting clarinet reeds gives the following upgrades in order: rapid fire, score x2, score x4, double shot, then the rest gives 500 points.
Bumping into a bubble or the edges will remove all upgrades, reverting the submarine back to its original state.
Bumping into too many bubbles or the edges will result in a game over.
