The main four play "guess who".
"Let's Play Guess Who" contains the following tropes:
- Dub Personality Change: When Mr. Cat says "happiness doesn't exist", the English dub has Kaeloo react angrily. In the French dub, on the other hand, Kaeloo is absolutely horrified by this statement and worried about Mr. Cat.
- I Resemble That Remark!: Kaeloo says she doesn't have a double personality... and transforms mid-sentence.
- Man on Fire: Mr. Cat sets Quack Quack on fire to pretend that he's Joan of Arc.
- Skewed Priorities: Quack Quack does a cool trick but refuses to teach Stumpy how to do it. Later in the episode,Mr. Cat sets Quack Quack on fire For the Evulz. Stumpy refuses to help Quack Quack put the fire out until he teaches him the trick, because learning a new trick is clearly more important than saving your friend who is on fire.
- Stylistic Self-Parody: Quack Quack squashes his head into a bizarre, bean-like shape and makes his eyes bug out of the sides of his head while imitating Stumpy.
