Noo-Noo takes the name from the robotic vacuum character in Teletubbies, a reference that turned unsettling once fans began using tubby-themed horror edits and games online. Tagged with FNAF, this short clip circulates in the same jumpscare culture as the FNAF Jumpscare Scream, where a sudden loud hit marks the scare instead of dialogue or music. Its appeal is the mismatch between a familiar children's character name and an abrupt horror sting, which makes it reusable for serious scares, parody reveals and gaming montages alike.
