Stumpy's latest act of extreme stupidity gets him killed. He meets the "spirit of morons", a magical spirit, who grants him one wish. He uses the wish to return to life as a genius.
"Let's Play Stumpy's IQ" contains the following tropes:

- Awesomeness by Analysis: Stumpy's intelligence allows him to analyze everything around him and find a way to make things go according to his plans.
- Cosmic Plaything: Stumpy is revealed to be a literal Cosmic Plaything, to the extent that the spirit of morons removes his super-intelligence because it makes him less funny.

- Everyone Has Standards: Even Mr. Cat is unsettled by Stumpy's idea of making a bomb and threatening to blow up the planet to achieve world domination.
- "Flowers for Algernon" Syndrome: Stumpy is granted intelligence by a spirit, but it turns out to be for the worse; he makes rude or brutally honest remarks (such as saying that Mr. Cat's drinking problem will make him obese), he tries to Take Over the World, and he tries to change the show's name from "Kaeloo" to "Stumpy".
