Wazzam was one of the wise Petpets involved in the founding of the University - specialising in magic. Their scrolls on topics such as Potion Theory are stored in the Secret Scrolls Club. He was apparently friends with fellow Founder, Rickles. Wazzam wrote a book called The Fire Sorceress, about a powerful fire magic user they once met.
Wazzam has yet to actually appear in the Park.
