One Potato, Two Potato, Sweet Potato, Amore

As part of a galactically-broadcast Candid Camera-esque program, Keroro plays a prank on Giroro, with the help of a Pekopon suit modelled after Natsumi, with Sumomo at the controls. Hilarity ensues as Giroro distracts himself from faux-Natsumi's advances with physical training and weapons maintenance - causing an exasperated Sumomo to attack Giroro, and incurring the wrath of the real Natsumi when she sees her own towel-clad self leaping across town. When she opts to stop them on her own, Kururu gives her his latest invention - the Natsumi battlesuit.
Natsumi finds herself stuck with Kururu's battlesuit, which has a tendency to activate when anyone nearby utters something even remotely sounding like the attack command. When the invade command kicks in, the battlesuit AI takes over Natsumi completely, causing her to destroy anything the Keroro platoon sends after her. Giroro is forced to confront her as well, and Kururu gives him the battlesuit deacivation code... "Natsumi, my love. Kiss me tender and hold me tight, forever!"
