The Jellyfish Fields Cliff is a cliff that appeared in the episodes: Patrick SmartPants, What Ever Happened to SpongeBob?, Slide Whistle Stooges and Pet or Pests. Most of the time, SpongeBob, Patrick or Squidward fall of it. In Patrick SmartPants, Patrick fell of it, and lost his head and exchanged it with, Brain Coral. In What Ever Happened to SpongeBob?, SpongeBob fell of it, and got a huge lump on the head. In Slide Whistle Stooges, Squidward drove and fell down with the truck he was in, while playing the Slide Whistles, and in Pet or Pests, Patrick and SpongeBob accidently roll down the Cliff.
Jellyfish Fields, of course!
