SpongeBob SquarePants (1999)

Sandy, SpongeBob and the Worm / Squid on Strike - S2-E18

Continuity mistake: In "Sandy, Spongebob, and the Worm," the worm is about twice the height of Sandy and Spongebob. Near the end of the episode, the Worm charges off of the cliff and when he reaches the bottom, and smashes the town, the buildings are tiny compared to him and the sea creatures are microscopic.

Sandy, SpongeBob and the Worm / Squid on Strike - S2-E18

Continuity mistake: In Spongebob, Sandy and the Worm, when Sandy ties the worm's tongue in a knot and they run from the worm, the worm opens it's mouth but you don't see the tongue tied in a knot.

Sandy, SpongeBob and the Worm / Squid on Strike - S2-E18

Continuity mistake: When Spongebob shows Sandy the paper clip and a piece of string the string is very small. Yet later after Sandy says, "no silly, how about s for saving our skins", the string is a lot longer.
