Sgt. Frog - Smurfmania is a 2020 fanmade collection of memes depicting depowered versions of Dororo, Tamama, Kululu, & Giroro (who are Keroro's beloved friends), which resembles Smurfs. It was inspired by Sgt. Frog Super movie 5, which is set in Easter Island in Chile. That setting is pretty rare to see in Anime & Manga in general. It was made by RFART419 on Instagram.
