Mermaid Man and Barnacle Boy IV / Doing Time - S3-E1
Plot hole: In "Mermaid man and Barnacle Boy", Plankton is shown as taller than the town at the end of the episode. However, when Spongebob is shrinking the people of Bikini Bottom, their sizes in the pickle jar seem to be equal with Plankton's actual height. In reality, Plankton should have been around the same size as the rest of Bikini Bottom's residence after the shrinking, not 5 times taller.
Answer: "The Secret Box", or maybe "Karate Choppers".
