Alien frogs come to take over the planet & get into all kinds of trouble while living under the roof of a small family.
The Hinata family has a new member - a frog from outer space! Keroro’s invasion of Earth doesn’t go exactly as planned, and he ends up running a vacuum instead of ruling the planet. But hey, at least he gets his own room!
Keroro searches for his lost platoon members. Meanwhile, Momoka has a major thing for Fuyuki. She also has something in her backpack with a cola addiction and an out-of-this-world problem.
