The (probably) last teaser for the platoon’s costumes for the musical has been posted! It’s the sarge himself! He looks pretty much how I expected him to, but I do like the swagger pose.

A couple of notes before we move on from this series of sneak peeks:

I’ve seen some people speculate that they’re gonna turn around and reveal that they’re wearing masks or face paint that look like the regular frog faces, but we’ve seen enough glimpses of foreheads/chins/behind the ears to debunk that, at least imo. It would be very funny/trolly if that was the case. But I think they might prefer the moolah they’ll get from billing attractive actors :V

I also saw someone on Twitter notice a detail that only Dororo doesn’t have those star-imprint jacket buttons, possibly because he’s a #rebel against the army which is a nice touch if intentional.

A brand-new Keroro project has been announced in the form of a musical stage play adaptation! It's called Keroro Gunso: the Pekopon Invasion Musical (Pekopon Shinryaku Musical Keroro Gunsou) and is set to begin running performances in September 2026. We don't have much information so far, but it's currently described as "A goofball comedic story featuring the Earth-invading Keroro Platoon and the Earthlings with whom they freeload, the Hinata family, depicted with techniques only a musical can deliver."

Here is the known staff for the production:

Original Work: Keroro Gunso by Mine Yoshizaki (Kadokawa); in Cooperation with the TV anime Keroro Gunso

Screenplay and Direction: Keita Kawajiri (screenwriter/director of Mob Psycho 100, Bobobo-bo Bo-bobo, etc. stage plays) of theatrical unit SUGARBOY

Music: Yu (vague) (Ensemble Stars, Price of Tennis, etc. stage plays)

Casting and other info to come at a later date!

After a series of teaser photos of the platoons’ outfits over the last few days, we finally have the full cast reveal! Not only that, the performance venue and dates have been unveiled as well!

The musical will be performed at Nihon Seinenkan Hall in Shinjuku, Tokyo across a series of nine performances from September 18–27, 2026. The full schedule is here. Ticket application/purchase periods will be staggered over a course of several periods starting on May 22, with the Keroro Fan Club getting first dibs.

In the midst of all this movie news, we’ve finally started getting some substantial hints about the musical, which until now hasn’t had any real updates since December.

Last Monday, we got a glimpse at what looks to be the outfits for the Keroro Platoon. Wait…those are pretty human-shaped… Could it be…?

Ahh…yep. So that’s what they’re doing huh.

I will be honest, I’m a scrimblo bimblo purist and not the biggest gijinka person (I like them when they’re unique but I still just prefer critters), so the fact that these might end up being inspired by the official handsome Keroro Platoon designs from a few years back isn’t to my tastes specifically—I was hoping maybe they’d do marionette puppets like the Digimon Adventure Tri stage play. But I realize that’s not very cost effective and, based on the interactions on the Kururu and Dororo teaser post, this is getting a whole lot of eyes on it, perhaps from people who are just shocked to see this direction for a funny mascot series xD

I am wondering if the plot/framing device will be similar to the official doujin, in that Keroro and co. turn themselves into attractive guys as an invasion tactic. The early posts on the musical’s social media account use hand puppets, so maybe they start like that in the beginning of the show before turning into the humanoid versions?
