Kenny the Cat is a SpongeBob SquarePants episode from season nine. In this episode, SpongeBob looks up to a new superhero: Kenny the Cat, a cat who can hold his breath for an incredible amount of time.
SpongeBob is excited because his brand new hero, Kenny the Cat is coming to town. Kenny is a cat who can hold his breath underwater for a really long time. Mr. Krabs is excited about Kenny's visit to Bikini Bottom too, so he decides to have Kenny appear at the Krusty Krab and give him the manager's treatment. SpongeBob goes to Sandy's house and tells her the news about Kenny coming to town, but Sandy thinks Kenny is a fraud because he never talks.
That night, SpongeBob and Patrick camp outside to see Kenny. They look at the stars and are overly excited to see Kenny.
The next day, Kenny the Cat finally arrives and starts giving out autographs. SpongeBob asks Kenny to autograph his custom Kenny spatula. He then invites him to the Krusty Krab. Kenny arrives at the Krusty Krab and Mr. Krabs gives him free ketchup packets and an all-you-can-eat buffet in his honor. He begins to strugle, as he needs to take a breath. He draws a toilet, and runs to the restroom. In the bathroom, Kenny takes an oxygen tank out from behind his back and uses it to breath. SpongeBob sees this and realizes that Kenny is a fraud after all. Kenny begs SpongeBob not to reveal his secret because he could lose his reputation and SpongeBob agrees.
When everyone is admiring Kenny and basking in his glorious fame, Sandy shows up and asks him some questions to expose Kenny. He opens his mouth but then, almost drowns so, he takes out his oxygen tank and reveals himself. This causes everyone to turn against Kenny and Mr. Krabs takes back the ketchup packs.
Howver, SpongeBob decides to help Kenny by giving him a suit and helment. He decides that Kenny should become a famous cat who lives underwater (like Sandy does). Kenny thanks SpongeBob for helping him, but sa
dly Sandy arrives and kicks Kenny and sends him back home to the surface. Even though Kenny is gone and can't really hold his breath underwater for that long, SpongeBob still admires him (much to Sandy's anger).
