The episode starts with Tiff collecting shells on the beach. Soon, she finds a golden shell with a love note from Kine. She finds Kine and tells how it is not possible that they be together due to the differences in their environments and refuses. King Dedede watches all this, and offers to make a deal that if Kine reveals his home's location, he would make it so Kine could live on land. However, Kine does not know that Dedede wants to build a resort in his home, and tells Dedede where it is. Dedede does partly keep his promise, by putting Kine in a large rolling aquarium on wheels! But Kine finds out life on land is rough, almost being sliced in half by Chef Kawasaki, nearly eaten by Dyna Blade, and falling from the sky into the mayor's house. Eventually, they find out what Dedede's true intentions are with Kine's home, Kirby stops him with Tornado Kirby, and the marine environment is saved. Dedede and Escargoon are chased away by Joe the Shark, and Kine finds new hope when Kirby is swimming with a snorkel. The episode ends with Tiff calling to Kirby that he's in big trouble for giving Kine the idea.
