In this online game, the player gets to take care of and nurture their own snail. They can choose the snail's shell color, name him or her, and come home to the pineapple under the sea in Bikini Bottom. Once the player is in SpongeBob's house, the player can spend hours entertaining their snail with toys like a ball of string or a laser pointer. The player can also give their snail a bath when it gets dirty, and feed their snail when it gets hungry.
Even though this game was based on the episode "Sanctuary!," it was released before the episode aired.

It is now possible to throw a party with the player's snail. If chosen, the player's snail will appear in the yard with other snails (two baby snails if the player's snail is a baby or one adult snail if the player's snail is an adult). The player will have to play with the laser and ball for a period of time and then feed the snails the cake.
