Peter Pettigrew was found, pretending to be a garden rat that one of the Weasley boys was keeping as a pet. Charlie Weasley, the second oldest and aspiring dragon-tamer, had grown curious about the health and longevity of his brother’s rat, and as such attempted to discover its magical properties—and instead found that it was Pettigrew, alive, albeit missing a finger. This, of course, led to much confusion, as Sirius Black was convicted in part for the murder of Pettigrew. Peter Pettigrew has since been brought to custody, and Black’s case re-opened.
