|“||Ten boys and girls fell on top of one another in an untidy hairy mess, clonking each other on the head with their wooden sticks. Within two minutes, Wartihog, Clueless, Lovethug, and Deadly Doris were lying stretched out on the ice||”|
|— Book 4|
Deadly Doris is one of the Bog-Burglar Tribe's teenagers participating in the "Young Heroes Smashsticks-on-Ice Competition during Freya's day Fete on the frozen-over Hooligan Harbor. Her team's opponents are the Hairy Hooligan novice Viking boys. She immediately jumps into a messy pile of bodies including Wartihog, Clueless, and Lovethug, only for all four to be knocked out cold. The Bog-Burglar team eventually win the competition.
Though Deadly Doris is not specifically described, she and her team members are described as "big, rough, mean-looking girls with wild hair, broken noses, and thighs like tree trunks." The one exception is Camicazi, who is very small.
