The show is titled Chou Musical Ban Keroro Gunsou Kocho Kocho Daisakusen Dearimasu! (roughly Super-Musical Version Sgt. Frog Kitchy Koo Epic War!; “Dearimasu” would be tough to translate here-- it's the same as the verb aru, to be, but much more formal) and features someone running around in a big green Keroro suit. Sounds cute!
