The Undie-taker (Patreon)

While working on the Rosalina variants, an idea for a monster came to me, one that would be more of a mischievous one.

So the gimmick for this monster is that although it has no dong like the other types of monsters it does have a strong urge to collect panties from girls (similar to the classic Rumiko Takahashi's character Happosai), but with the twist that it also swaps the panties of the victim with another ones, mostly being some embarrassing ones and flashing them for everyone to see.

Then fleeing the scene leaving the victim with its undies exposed to her luck.
