Kaeloo, Stumpy and Mr. Cat play baseball against Quack Quack, Olaf and Serguei. Realizing that their opponents are too skilled, Mr. Cat's team resorts to cheating.
"Let's Play Baseball" contains the following tropes:
- Aesop Amnesia: Kaeloo seems to have forgotten the lesson from "Let's Play Golf".
- Baseball Episode
- Bubblegum Popping: Kaeloo blows a bubble out of her gum, which pops and gets stuck all over her face.
- Bunny Ears Picture Prank: When both the baseball teams get their pictures taken, Kaeloo does this to Stumpy (who is on her team).
- Distracted by the Sexy: Invoked by Mr. cat's baseball team. They get Eugly to stand next to the baseball field when Quack Quack (who is playing for the opposite team) is playing. Quack Quack gets distracted and misses the ball each time.
- Downer Ending: Kaeloo, Stumpy, and Mr. Cat win the game.
- Happy Dance: Stumpy does one involving pushing his arms back and forth while walking on the spot. Later in the episode, Kaeloo joins him in doing it.
- Huddle Shot: Used while Kaeloo, Stumpy, and Mr. Cat discuss strategies on how to defeat their extremely talented opponents.
- I Have Nothing to Say to That: Played for Laughs. Mr. Cat realizes that the only way his team will win is to cheat, and Kaeloo is horrified by the idea, but he points something out:
- Karma Houdini: See Downer Ending above.
- Out-of-Character Moment: Kaeloo agrees to go along with Mr. Cat's plan to win by cheating.
