Let's Play Simon Says
- Quack-Quack and Mr. Cat are shown looking at dirty magazines. Yes, the pictures are actually shown on-screen.
- At the end of the episode, after Mr. Cat has been beaten into shapeshifting into a book, Kaeloo decides to read him to her other friends. As soon as she opens him, the screen goes black, coupled by a gasp and somewhat excited-sounding "Mr. CAT!". The original French version has her exclaiming "Ooh la la!". Both versions heavily imply she saw his goods, and that she likes what she sees. Given that in the English dub, she was re-written as male until the 11th episode...
Let's Play Happy Rotter
- Mr. Cat tells Quack-Quack to take off his underwear, complete with upbeat music and a disgusted reaction from Mr. Cat. It turns out Quack-Quack is wearing a diaper underneath, which Mr. Cat laughs at once he gets the courage to actually look in his direction.
Let's Play Peace Man
- Stumpy refers to the part of a documentary he expects a pair of crepidula to start mating on-screen as the "interesting bit". This is followed by a Head-Tiltingly Kinky moment when one of the crepidula changes sex from male to female.

Let's Play Baby-Sitting
- Mr. Cat pins Kaeloo to a couch arm and rubs his groin against hers suggestively before turning the lights off, declaring that he is "exercising his marital rights" before a comical honking sound effect is played while he moves forth slightly, bearing a cheeky grin. At this moment, Kaeloo reacts angrily.
Let's Play Air Pockets
Let's Play Treasure Hunt
Let's Play Time Travel
- Stumpy asks Kaeloo to be "lovers" with Mr. Cat so they can produce a baby. Kaeloo, having just given him the (incomplete) "talk", likely knows all about how reproduction works, and she agrees to do this. When she and Mr. Cat are on a date later on in the episode, she makes a blatant attempt to seduce him, which ends in Mr. Cat pretty much attempting to force himself on her with a crazed, hungry look in his eyes. Thankfully, nothing actually happens.
