Mr. Cat has been bullying Stumpy and taking his things, so Kaeloo teaches him self-defense.
"Let's Play Smileyland Wrestling Championship" contains the following tropes:
- Arrogant Kung-Fu Guy: After Stumpy manages to beat Mr. Cat in a fight, he briefly becomes very arrogant. The problem quickly fixes itself when he tries to attack Quack Quack, who manages to easily defeat him.
- Doppelgänger Attack: Stumpy uses one on Mr. Cat.
- Fartillery: Stumpy weaponizes his farts by using them to launch himself into the air.
- Flashback Twist: Stumpy tells Kaeloo that Mr. Cat forced him to give him all his comic books. When Kaeloo asks how it happened, a flashback is shown where Mr. Cat menacingly approaches Stumpy and demands the comic books... and Stumpy nonchalantly handed him the comic books and said "Okay".
