Stitch was created for Disney's 2002 animated film Lilo & Stitch, where the alien Experiment 626 is voiced by co-director Chris Sanders. His squeaky voice and distinctive giggle became one of the character's trademarks as the film grew into a franchise with sequels, series and merchandise. Clips of the laugh later circulated on soundboards and in short video edits, detached from specific scenes and used as a standalone reaction. Its continued popularity comes from how recognisable the tone is, even for viewers who have not seen the film recently.
