My Pretty Seahorse 037

When SpongeBob arrives at work the next morning, he leaves Mystery outside at the bike post. Scooter and Wobbles approach Mystery and mistake her for a kiddy ride. Wobbles suggest Scooter try it out, and when he inserts a coin into her "slot," Mystery kicks him into the distance and he blows upon impact. Wobbles run away screaming, causing Mr. Krabs to come out and see what the trouble is. He sees Mystery and mistakes her for a monster; SpongeBob tells him she is his pet, but even though she is harmless to SpongeBob and not the others, he is ordered to get rid of her and if he disregards his order, he will be fired for not cooperating with him.

SpongeBob attempts to hide her in a cupboard in the kitchen until Patrick finishes building a stable. SpongeBob offers Mystery a Krabby Patty, which she begins craving after eating. While he initially avoids being caught sneaking Mystery into the kitchen, SpongeBob gets in trouble when Mr. Krabs comes out of his office a second time and witnesses him curing a sick Mystery, who had developed a stomachache from consuming various objects moments prior. Mr. Krabs is upset with his employee and tells SpongeBob that the horse has got to go, but he is extremely reluctant to proceed due to great sentiment.

Mr. Krabs, feeling sympathy for SpongeBob, tells him a story of his favorite dollar and how he eventually spent it for a soda on a hot day. He tells SpongeBob that Mystery needs to be freed because the indoors are not a place for a wild animal, and SpongeBob consents and takes Mystery out the front door, where he painfully asks her to leave. Mr. Krabs tries to comfort SpongeBob until Squidward shows him an empty safe. Realizing that Mystery ate the Krusty Krab's finances, SpongeBob and Mr. Krabs chase after her, disappearing into the distance. The episode ends with Patrick trying to enter a hat store, but the wooden board nailed to his head blocks his way.
