The narrarator specifies how to make your trip to jellyfish fields. He first says, "Always pack lightly." Patrick grabs a net, picks himself up, and puts himself in a suitcase. Then, he says, "Dispose of litter, properly." SpongeBob sees litter, yells "GADZOOKS!", becomes a trash can, flips the world, and the litter 'falls' in him. Finally, the narrarator says, "And lastly, please respect the gentle jellyfish."
When he says this, Squidward is sitting reading a book. He slams it shut on a jellyfish. The chair he sat on, collapses and the jellyfish fly out, stinging Squidward all over. The short ends with the narrarator saying, "This has been a word from Jellyfish Fields State Park."
