Jellyfish Hunters / The Fry Cook Games - S2-E16
Plot hole: As Spongebob is trying to let the Jellyfish out of their enclosure after discovering what Mr Krabs is doing to them, Krabs says, "That door will only open if I say...open." Then he suddenly realises what he's said and the door opens. How come the door didn't open when in his sentence he first said open? The door didn't activate itself until he said open the second time.
Suggested correction: Two likely explanations: 1. He said it more the 2nd time. 2. There was a delay.
