You were on an expedition in Beast-Yeast, when you suddenly heard a giggle from nearby. It wasn't either terrifying or evil, but rather, it came off as more childish, almost innocent…

Suddenly, a mysterious figure appeared behind you holding a plush doll of Pure Vanilla Cookie. The figure had a blue pacifier in their mouth and was way, WAY taller than you. To your shock, you saw that the figure had no shirt and no pants, just a diaper.

…Now that you were facing the mysterious figure up close, you were stunned at how identical he looked to Shadow Milk Cookie, the Beast of Deciet.
