He has lived on only 30 minutes of sleep a day for 17 years. His motto is "Sleep is the root of all illness," a claim that defies all medical logic. He spends about five hours a day weightlifting. He runs something called a "Sleep Improvement Program," though his actual intentions are baffling. He gets furious if anyone suggests that longer sleep is better. If you say anything like "Maybe you should get some sleep," he will grab a dumbbell and try to kill you. Technically, he has a good personality deep down.

A creature that looks like a cross between a mole and a cat. They appear frequently in summer, digging holes and ravaging fields. They live both in groups and as loners. They are incredibly persistent and can dig through concrete to escape. They hate water. Occasionally, they will resort to cannibalism if they get agitated. They follow the orders of the "Boss Kuiya." Their cry sounds like "Wahoo!" and they are very aggressive. They are roughly the size of a cat. When they sense danger, they let out a scream that summons the Boss Kuiya.

A creature one size larger than a standard Kuiya. It emerges from underground whenever it hears a Kuiya's scream. It lives a lazy lifestyle, using other Kuiya as its lackeys. However, its digging power, persistence, and sheer audacity are top-tier, possessing a sense of conviction (?) worthy of its name. It can dig through concrete with ease. Its cry is "Wahooo!" It eats trees and will actively try to kill you. It is roughly the size of a car.
