This clip is a fan-made meme mashup rather than a line from a Harry Potter film, pairing Dobby's distinctive house-elf voice with Fortnite's V-Bucks economy and its Scooby-Doo cosmetic. That unlikely crossover is the whole joke, turning a character famous for wanting freedom into one obsessed with buying a cartoon skin. Shared on soundboards and in short gaming videos, it has stuck around because it is instantly recognisable to both Harry Potter fans and Fortnite players, and it fits neatly into shop, spending and reaction edits.
