Grandma's Kisses / Squidville - S2-E9
Continuity mistake: When Spongebob stops crying, his grandma pulls a plug out of the floor to drain the water, but in a later shot through a window, the plug and hole are gone.
Continuity mistake: If you look carefully, you will notice that on the title sequence, patchy the pirate's eyepatch changes eyes. This varies from episode to episode.
