Keroro Killed The Radio Star!

Low on invasion funds, the platoon takes on food vending and gaming jobs at a festival. Keroro's unscrupulous manners are challenged by Natsumi and they face off at a turtle fishing game. Defeated, the frogs are ready to leave the festival, until Natsumi told them that as long as they are legitimate, it doesn't matter who attends the festival. Stirred by her compassion, Giroro dashes to stop Keroro trump card, but instead find himself, Keroro, and Tamama sent into the air as part of the night's fireworks. The red and green are exceptionally beautiful, but no one can see the dark blue color of Tamama.
Witnessing the power of radio, the platoon, minus Dororo, set out to jack all the stations and put on their own programming. Different and novel at first, the radio progam gains a huge draw. However, a poorly impersonated Sumomo-chan by Giroro quickly reverses that and soon listeners turn off their radio one by one.
