Keroro Gunso A.K.A. Sergeant Keroro
Anime Cartoon Series: Season 01; Episode #09: "Hinata Aki, A Dynamite Woman" (05/29/2004)
Natsumi's mother Aki is ARed from adult to preteen. One of the frog aliens is ARed from adult to baby. Aki is nostalgic about her school days and decides to go to her son and daughter's school wearing one of her son's uniforms. Apparently her daughter's school uniform was too big or unavailable. At school she is oddly enough mistaken for her own son Fuyuki.
Aki addresses one of the girls familiarly (Momoka-chan), who assumes it's a confession from Fuyuki. Aki also plays some killer soccer against her daughter Natsumi (a top soccer player at the school) and wins! The real Fuyuki is confused by the acclamations after Mama leaves. Aki is APed back at the end of the episode. The AP RN scene is wonderful according to Tacostar. In #18 APed Natsumi looks kawaii in a bikini. (AR, AP RN)

Kururu's AP gun shows up again to allow Keroro-tachi to go to a ski resort after Natsumi's mom Aki says they must have adult supervision. Natsumi was once again "conscripted" (i.e. age zapped) to perform that role. The AP process and return to normal were not shown.

We find out there is one sport that Natsumi is not good at. In the manga ski trip, there was reportedly an explosion and a naked grown up Natsumi. (APed AA aftermath)
