This article contains plot details from the latest books.
Fluffy is the Tyrannosaurus rex Prattles pin that resides on the bandage on Sophie's wrist. Introduced in Flashback Fluffy was named by Keefe Sencen presumably because Tyrannosaurus rexes are covered in fluffy feathers. Fluffy has several Prattles pin friends on Sophie's wrist, such as Krakie, The Stink, Bitey, Scaley Butt, and Cheeky. The pins are there for moral support after Sophie broke her arm after being attacked by the Neverseen at the beginning of the book.
