Princess Bubblegum (Bubblegum Slime Girl / Monster Girl)

Based on the Monster Musume anime. After the fall of the lost city of New Forosa, many monster girls fled. Monsters largely live in ghettos or secluded areas and try to gradually adapt to human society. But the process is slow and they suffer a lot of discrimination.

It's Bonnibel from Adventure Time.

She looks like a young woman with long hair, but her entire body is composed of a homogeneous mixture of pastel pink chewing gum.

Princess Bonnibel "Bonnie" Bubblegum (often called PB and occasionally Peebles, Bub-Bubs, or P-Bubs)[5] is one of the main characters of the series Adventure Time and first appeared in the animated short.

Princess Bubblegum is the current incarnation of the Candy Elemental. This is comparable to the inhabitants of the Candy Kingdom, who are all composed of types of desserts and candies. She rules over the Candy Kingdom, but in the Season 6 episode "Hot Diggity Doom" (the first part of the season's finale), an election was held and she lost to the King of Ooo by a landslide. As a result, she no longer ruled the Candy Kingdom and the King of Ooo replaced her as the new ruler until a rebellion against the King of Ooo allowed her to reclaim the throne in "The Dark Cloud".
