Sandy's experimental teleportation device malfunctions, melding SpongeBob and Squidward into one body. This makes working in the kitchen and behind the check out counter at the Krusty Krab a bit of an issue. But Squidward's main concern is his big clarinet recital that's just one day away. Unless Sandy can reverse the effects of her machine, Squidward will have to find a way to hide SpongeBob during his performance.
