The main four start their own circus.
"Let's Play Circuses" contains the following tropes:
- All Animals Are Dogs: Bad Kaeloo sticks out her tongue and wags her "tail" like a dog.
- Brief Accent Imitation: Mr. Cat does a horrible attempt at speaking with an Italian accent. When asked why, he admits that he has no idea.
- Cartoon Juggling: The "shower" type is used when Stumpy juggles chainsaws.
- Circus Episode
- Delayed Reaction: Bad Kaeloo actually acquiesces to Mr. Cat's demands for a few seconds before realizing.
- Hi, Mom!: Inverted. Stumpy's mom sees him on TV and calls him on his phone.
- Juggling Dangerously: Stumpy juggles chainsaws. It goes well until his mother calls him on the phone, having seen this on live TV and wanting to make sure her kid is safe. He neglects the chainsaws in the air and picks up the phone.
- Out-of-Character Moment: When Mr. Cat sees a missile coming his way, he yells at it to sit down instead of getting out of its way.
- Running Gag: People telling Stumpy to be a clown instead of whatever job he wants to do.
- Tightrope Walking: In the Circus Episode, Quack Quack, who is known in-universe for doing things that are Beyond the Impossible, manages to do this without a rope to walk on, by balancing on thin air. The act is called "Tightrope walking on a rope that doesn't exist".
