Plot.
Mr. Krabs sees people going to Goo Lagoon, a beach, so he goes there to sell Krabby Patties. SpongeBob, Squidward, and Mr. Krabs get on a surfboard and find Patrick and Sandy. Patrick tries to get on the surfboard, but he causes it to fall and it gets into a giant wave that separates everyone. SpongeBob, Patrick, and Squidward end up on an island with other surfers. Mr. Krabs is all alone in the middle of the ocean with his cash register, Cashy. Sandy gets put on a different island and builds a helicopter.
The surfers tell SpongeBob, Patrick, and Squidward that the only way to get back to Bikini Bottom is to surf there, but they do not know how to. One of the surfers, named Twitch, tells them that the only person who can teach them is a surfer named Jack Kahuna Laguna. Once the three find Jack Kahuna Laguna, he comes out a hut with a long surfboard and says that they have to ride a big wave called The Big One to get back home. They practice surfing to get ready for The Big One. Before they start surfing on The Big One, Jack Kahuna Laguna says that it wants a sacrifice.
SpongeBob, Patrick, and Squidward surf The Big One and find Mr. Krabs and Cashy. Mr. Krabs gets on the board but drops Cashy. Jack Kahuna Laguna goes and gets Cashy and acts as the sacrifice. Once the wave disappears, SpongeBob, Patrick, Squidward, and Mr. Krabs are near Goo Lagoon. Sandy's helicopter crashes into Goo Lagoon as well. The people in Goo Lagoon throw a party for them coming back.
