The main four and the bunny twins go to the beach, where they decide to play volleyball. Unfortunately, Stumpy is terrible at the game. Meanwhile, Pretty tries to seduce Mr. Cat, but he's not interested.
"Let's Play Beach Volleyball" contains the following tropes:
- Beach Episode: The entire episode takes place on the beach.
- Failure Montage: A montage is shown of Stumpy losing at beach volleyball. The final scene in the montage makes it look like he's going to finally hit the ball, but he fails that too in an Epic Fail.
- I'm Standing Right Here: Pretty reads on the internet that boys love to comfort miserable girls and tries to get attention from Mr. Cat by telling him that she finds life with her sister unbearable and wants to commit suicide, while her sister is standing right there.
- Lame Pun Reaction: At the end of the episode, Mr. Cat makes a stupid pun. Kaeloo and Quack Quack simply walk away with bored expressions on their faces.
- Love Potion: Pretty buys a love potion so she can get Mr. Cat, who absolutely despises her, to fall in love with her. She puts it in a glass and asks Mr. Cat if he is thirsty and wants a drink. Unfortunately, Stumpy, who is extremely thirsty, walks up behind her, snatches the potion and drinks it up. To Pretty's disgust and horror, Stumpy falls in love with her instead of Mr. Cat.
- "Pop!" Goes the Human: Happens to Stumpy as a result of taking too many of the pills he ordered on the internet; he winds up getting inflated instead of getting muscular, and pops when trying to hit a volleyball.
- Weight Woe: Kaeloo decides to play volleyball because she realizes that she's getting fat; however, the plot becomes so sidetracked by the end of the episode that the audience never finds out if she ever did lose the extra weight.
