[Cuts to Jellyfish Fields where SpongeBob is riding on Patrick's back like a horse and catches a jellyfish in the net. Another crater comes back. Cuts to SpongeBob and Patrick licking the sand and as SpongeBob is licking, his nose grows back to normal size. Cuts to Patrick and SpongeBob standing on their hands] Talk backwards.

SpongeBob:
Tap, erus uoy era? (Are you sure, Pat?) [SpongeBob's legs and arms are back to normal]
