Haggis (character)

Goodbye, Haggis. I'll never forget you. You're the best bearded, sloppy, giant friend a wizard could ever have.

Haggis is a giant in the Henry Skreever book series. He is a parody of Hagrid from Harry Potter. He briefly appeared at the end of "Prunella Sees the Light" saying goodbye to Henry before he goes onto the train.
