Balloon Travel
When the anglerfish who had chased after SpongeBob's balloon earlier brings it back, SpongeBob tries to explain to him that he has a bigger problem than that as he can't get home, while anglerfish fills the balloon with air. It's only when SpongeBob rises off the ground does he learn anglerfish was helping him to float back home. When SpongeBob offers his gratitude to him in with a Rock Bottomite accent, he finds the anglerfish can speak just fine.
