SpongeBob and Patrick's club is too small for Squidward... literally. But Squidward forces his way in, "propelling" the clubhouse into the middle of nowhere. It's spring in Bikini Bottom and SpongeBob finds a wild seahorse and decides to keep her. He names her Mystery and he keeps on confining her into small, cramped spaces, so she becomes unhappy. Mr. Krabs convinces SpongeBob that releasing her is the right thing to do.
