Fanon Discontinuity: This is undoubtedly one of the show's most despised episodes, due to its mean-spiritedness towards Sandy and Spongebob's mind-boggling stupidity.
Funny Moments: As drab as this episode is, the random bit of Mr. Krabs wearing a maid uniform while vacuuming his safe is worth a chuckle.
Squick: Plankton traveling around inside Sandy's lifeless fur makes it look too much like a corpse.
The Inside Job
Nightmare Fuel: Plankton's brain connector causing him to transform into SpongeBob and then Patrick can be seen as unsettling, and seems to borderline on Transformation Horror.
