Laa-Laa is the yellow Teletubby from the children's television series Teletubbies, reimagined as a monster in Slendytubbies, a fan-made horror game inspired by Slender Man. In the game, the familiar characters become hostile creatures that hunt the player, and their distorted voices turn something nostalgic into something frightening. Clips of the game spread through horror gameplay videos and meme edits, where the scream became a shorthand for innocent characters turning scary. It is still used because that contrast between a beloved children's character and a horror scream is instantly recognisable.
