Dr. FlipFlop is a four-eared, anthropomorphic rabbit and is one of Wakoshi's childhood imaginary friends. He is known to be silly, eccentric, erotic, energetic, playful, and goofy. Dr. FlipFlop is best at surgery, science, and mechanics. Wakoshi created Dr. FlipFlop because he saw an extremely skilled man who is known to be clumsy but always keeps a positive mood as of means to not let his patients down. The doctor sadly passed away because of a car accident while on a way to perform surgery on a kid who was on a verge of death. With a voice that mimics that of Tristan from the Yu-Gi-Oh Abridged series, as well as having an energetic and entertaining personality like Tigger, this guy puts positivity to the next level. Also, whenever Wakoshi is injured or at the verge of death, Dr. FlipFlop emerges into reality on his own to perform medical treatment. When summoned at will by Wakoshi, he can use his skills to perform medical treatment, work on mechanical stuff, or perform scientology whether it's lab experiments or performing biological tests. Dr. FlipFlop's abilities is stomping, leaping at great heights (Sheila the Kangaroo), and casting Dia (SMT/Persona).
