Sandy's Rocket / Squeaky Boots - S1-E8
Continuity mistake: In "Squeaky Boots", Mr. Krabs starts hearing squeaky sounds everywhere. Then he goes mad and says he took the boots from SpongeBob. At this point, notice the restaurant floor's colour. Mr. Krabs lifts the whole restaurant, but we can still see some floor (where Krabs is). Notice that now the colour of the floor has changed.
Answer: "The Secret Box", or maybe "Karate Choppers".
