First seen in Episode 7. Upon visiting the 2D dimension of Soul Eater, Grimsley had discovered the mightiest form of waifu power in the form of Maka Albarn's legs. Stricken with a boiling erection of a thousand suns, Grimsley immediately used his Cookie Butter abilities to snag not only Maka, but also her legs.

In his signature fight with the illustrious yet fucking stupid Jimmy Brando, Grimsley used the power of Maka's Legs to counter Jimmy's Za Warudo. However, due to the immense waifu power, Grimsley was stricken with yet another case of lower-body rigor mortis and immediately fled to soothe his nerves.
