Grampu is one of the main characters on Edgy Oobi.
Grampu is Oobi and Uma's grandfather. He claims to be only seven years old but is clearly much older. For most of the series, he has a job as a snake milker. However, in episode 5, he doesn't milk enough snakes and gets fired by his boss. He gets a new job at the end of the episode, but his new workplace hasn't been revealed as of yet.
He almost always addresses other people as "phat" or "bish."
Like his family members, Grampu is a hand puppet with no accessories or clothes. Just like his grandson Oobi, he has red googly eyes. The only difference between Oobi and Grampu's appearances is that Grampu has his fingers curled up in the front.
Grampu has appeared in every episode of the main series so far, but is absent for two Oobi Show clips.
