"… 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 –"
-- Luna Lovegood (HBP19)
A burly Hufflepuff Quidditch player – Chaser – who Luna misidentified during the match with Gryffindor. She thought his name might be Bibble or Buggins (HBP19). During the match, Cadwallader scored at least two goals.
This surname is shared by Eurig Cadwallader, who played seeker for the Wales National Team at the 2014 Quidditch World Cup (Pm). It is possible that this is the same individual. -BB
