The warriors Super Fumina and Hyper Gyanko search the countryside for the castle of Evil Mold Miyaga. They encounter Bearbear Village, which is filled entirely with Petit’GGuys. They both exclaim in excitement over how cute they are, which sends the Petit’GGuys scrambling. Chinagguy appears and demands that Fumina and Gyanko leave the village. Fumina and Gyanko explain that they’re warriors of justice, but Chinagguy has never heard of them. Chinagguy invites them in and explains that two nights ago, UFO-like objects came and abducted all the Beargguys. Chinagguy told all the Petit’GGuys that their parents were out on errands, but she suspects that some know the truth. Fumina and Gyanko head in the direction the UFOs went toward the beach, and they’re shocked to find all the Beargguys hanging on racks. They come under attack from a UFO that Fumina thinks looks like a Bug from Gundam F91. They destroy the attacker and discover that it’s an Acguy head. Fumina doesn’t understand, so Gyanko explains that since Beargguys are derived from Acguys, the plastic runners feature extra parts that aren’t needed for construction – namely, Acguy heads. Gyanko thinks that the Acguy heads hold a grudge over Beargguys because they don’t get to live as complete Gunpla. Fumina and Gyanko then come under attack from a large horde of Acguy heads. The two initiate a dual transformation and become Command Fumina and Rick-Do Gyanko. They destroy several Acguy heads but are ultimately overwhelmed and have all their armor destroyed. The Acguy heads coalesce and form a massive Acguy that attacks them both. The giant Acguy closes in, but Fumina and Gyanko are re-energized by Gunpla LED units held up by Chinagguy and the Petit’GGuys. Fumina and Gyanko say that they understand the wish of the Acguy heads to live as complete Gunpla. Fumina summons the Star Winning Gundam and takes on its armor to become Winning Fumina. She attacks with the Falling Star Rainbow, which will send the Acguy heads back to the Gunpla factory in Shizuoka, where they will be reborn as new Gunpla parts. With the Acguy heads gone, the Beargguys are able to return to their village in peace. Fumina and Gyanko depart to continue their search for Miyaga.
This episode goes down a completely different route by focusing on the Gunpla as characters rather than their actual human builders. Instead of having Fumina and Kaoruko (Gyanko), we’re seeing Gunpla representations of them in a story that parodies magical girl anime. Children’s anime tropes are also parodied, including a request that viewers hold up the merchandise they purchased to help power up the heroes. Despite the magical girl focus, there is some odd fanservice here, including bits of Fumina in skimpy outfits between transformations. It seems odd to have male-focused fanservice in a story parodying anime targeted at girls, but then again, the director for these shorts is Masami Obari, so perhaps it’s not that surprising.
