Frog invaders attempt to take over the Earth.

Momoka has a major thing for Fuyuki. She also has something in her knapsack with a cola addiction and a farting problem.

Suffering under house arrest puts the Sergeant in a bad mood that stinks up the Hinata household worse than day-old diapers.

Gororo's the new frog in town; he's rough and tough and determined to take over the Hinata family's home so they can use it as a base of operations, which involves first getting rid of the current residents.

Keroro's assignment is supposed to be taking over the planet, but now that he has a pocket money, all he wants to do is visit the local toy shop.

Momoka invites Fuyuki on a romantic trip to the beach. Unfortunately his family, a ghost, and a few amphibious intruders get in the way.
