HUFFLEPUFF
- Luna: "... but now that big Hufflepuff player's got the Quaffle from her, I can't remember his name, it's something like Bibble - no, Buggins -"
- Professor McGonagall: "It's Cadwallader!!!"
- — Luna Lovegood's commentary on a Quidditch match.
Cadwallader was a wizard who was Sorted into Hufflepuff house at Hogwarts School of Witchcraft and Wizardry. He played the position of Chaser on his house's Quidditch team.
In 1994 he was next to Anthony Rickett during the First Task of the Triwizard Tournament.
In 1996, during a match against the Gryffindor Quidditch team, commentator Luna Lovegood could not remember Cadwallader's name, calling him "Bibble" and "Buggins" before Professor McGonagall corrected her.
Cadwallader fought in the Battle of Hogwarts. He fought several Death Eaters after Voldemort's speech. Cadwallader survived the battle.
