The Badabook (not to be confused with The Babadook) was a guest at the 2019 Bi-Annual Vampire Orgy. He appeared in What We Do in the Shadows (TV series).
He attended with his cousin Sylvia and met Nadja for the first time, explaining that his name was a pun on "bada bing, badabook". He left the orgy early with all the other guests after Laszlo Cravensworth destroyed the mood by publicly declaring his love for Nadja and inviting her to a two-person orgy upstairs.
