Trivia: When Carly is watching TV, you can hear the TV playing a clip from "Drake and Josh" where Megan is pulling a prank. Carly says "Why can't I pull pranks like her" or something like that. Carly and Megan are both the same actress, Miranda Cosgrove.
Answer: In direction translation it means 'Mischievous Spirit'. 'Hob' as in HobGoblin means clown or prankster, and 'Knocker' was an old age term for Poltergeists in mines. Miners would often complain of hearing knocking sounds down mines when there was no-one else down there, hence 'Knocker'. It's not a regular English expression though.
