A young Keroro tries to impress Pururu by showing off the Kero Ball, a ball borrowed by Giroro from his brother Garuru. While testing the buttons, he accidentally transports the four tadpoles inside the ball. To get out, they must win the pinball maze. In the outside world, a young Kururu picks up the ball and hears the cries of help. He makes a deal to free those trapped inside if he gets a plate of curry rice. A deal is a deal and with the Kero Ball, a plate of curry rice is produced for Kururu. Unfortunately, the plate grows bigger and bigger and bigger. It gets so big, that Kururu was immersed in the curry. The yellow curry slowly transforms the blue Kururu into the "yellow devil", and as the film is about to fade to black, "Kukuku" is heard.

One day Giroro shows up at the base with something new and exciting, the Kero Ball, a device that owned by his older brother Garuru. Every one is excited to see what the Kero Ball can do, especially the young and juvenile Keroro. He quickly snatches the ball away from Giroro and begins to play around with it. They get some food from it which appeals to Pururu. Zeroro comes in and falls on Keroro, who drops the Kero Ball, causing the tadpoles to be warped inside of it. Now the young tadpoles must overcome obstacle after obstacle in order to escape their dark prison and unravel the mystery of the Kero Ball. Luckily, Kururu and his siblings Rinono and Shupepe appear.
