Plankton demonstrates many different evil laughs in a recording. He is shown to laugh inside of the Chum Bucket in different spots and outside when sitting on a chair and eating popcorn.
- This short is the sequel to "Plankton's Diary: Karen."
- Clips from "Move It or Lose It" where Plankton waits to watch the Krusty Krab get destroyed are seen when Plankton mimics SpongeBob's laugh.
