Alt spelling is "Puuchu".
Alien creatures that have found their way into the anime Excel Saga. When alive they resemble sort of mutant teddy bears, however a thwack in the nose will not only kill them, but they mutate to a form where their face somewhat resembles Al Jolsten's. Their special abilities are to overpower people with their deception by sheer cuteness. Their name is derived from the only sound they make when they're not being killed. (They tend to say things like "Ah, that hurt!" as they die.)

Chad: Yo! Brad! I heard you pulled a Poochoo Nut last night!
Brad: Yep. Not my proudest moment. The Misses wasn't happy.
