SpongeBob, Patrick, Squidward, and Sandy are realistic sea creatures hanging out on the Bikini Atoll island. The player can use the mouse to click on a character and move the character around until the player lets go of the mouse. The player can press the left or right arrow keys to move all the characters in that direction. If the player moves a character off the island, they will just come back up onto the island. The player can press the space bar to shake things up (cause an earthquake) on the island. On the island behind the characters are some objects the player can click on.
One of the objects is a bottle with a piece of paper inside and if the player clicks on the bottle, it will show a list of fun things to do in the game. There is a tropical island tree that the player can click on to make coconuts fall from. Sometimes in the game, random objects fall onto the island. The player can click on an object that fell onto the island and drag it to a character to let them interact with it.
On the island behind the characters is a treasure chest. If the player clicks on the treasure chest, it will show the random objects you have found on the island. Occasionally in the game, seagulls come to attack the characters on the island. You prevent this by clicking on the seagulls to shoo them away. The player can click the sun or moon in the background to change the time to night or day.
The game never ends until the player chooses to quit the game.
