In this 26-minute-long special, Kaeloo and Mr. Cat accidentally destroy Smileyland and the main four must work together to rebuild it.
"Let's Play the Very Special Episode" contains the following tropes:
- Agony of the Feet: One of the mini-Bad Kaeloos bites Mr. Cat's foot.
- Anthropomorphic Personification: A slight variant is used. The main four use a machine to extract the bad thoughts in their head, which are then personified as miniature versions of themselves. For example, one of Mr. Cat's thoughts, which represents greed, is portrayed as a miniature version of himself holding stacks of cash and yelling about how nobody can touch any of it.
- Art Shift: Kaeloo interrupts the theme song and complains about it before making her own 2D intro to the show.
- Aside Glance: Mr. Cat has an Imagine Spot of himself being massaged by several clones of Kaeloo. The real Kaeloo, standing next to him, gives an annoyed look to the audience as all she can see is Mr. Cat blushing and drooling.
- Baby Talk: Mr. Cat does this to one of the miniature Bad Kaeloos.

- Book Ends: The episode's conflict starts with a fight between Kaeloo and Mr. Cat and ends with them reconciling and Holding Hands.
- Cerebus Call-Back: This episode shows flashbacks to several episodes where Stumpy was abused or made fun of by his friends. Those episodes are funny to watch by themselves, but not when you see the poor kid remembering them with tears in his eyes and the other three realizing with dismay just how cruel they've been.
- Christmas Episode: The episode starts with the main four celebrating Christmas on August 13th.
- Continuity Cavalcade: Kaeloo, Quack Quack and Mr. Cat see a bunch of screens depicting almost every time in the show so far where they abused or made fun of Stumpy.

- Force-Field Door: The door leading to the magical staircase is a force field door. Only the Pure of Heart may pass through it; anyone who isn't pure gets an electric shock.
- Foreshadowing: Episode 63 and Episode 72 foreshadowed the events of Episode 105, namely Stumpy becoming evil and taking control of the world.

- Holding Hands: Realizing that they are about to be erased from existence, Mr. Cat softly smiles at Kaeloo and holds her hand.
- Hostile Show Takeover: Stumpy breaks into the animation studio making the show and takes over script-writing.
- Hypocrite: Kaeloo is perfectly fine with ruining Mr. Cat's plan to sunbathe and relax by turning it into a snowy day, but the moment he turns her snowy day into a sunny one, she starts yelling at him. Somewhat justified in that Kaeloo did her best to accommodate Mr. Cat's needs by providing him with a fireplace and a cozy couch to curl up on.

- Not So Above It All: Mr. Cat suffers from Cuteness Proximity upon seeing the mini Bad Kaeloos and starts using Baby Talk with them.

- Silent Treatment: Kaeloo decides to give this to Mr. Cat until she finds out that he's innocent.

- Stylistic Suck: Kaeloo introduces all the characters in the style of moving drawings on a sheet of ruled paper, and her drawing of Stumpy is absolutely terrible. Lampshaded by Stumpy himself.

- You Called Me "X"; It Must Be Serious: While desperately trying to convince Kaeloo that he's telling her the truth, Mr. Cat uses her real name instead of a nickname.
