The Grinch comes from Dr. Seuss's 1957 book How the Grinch Stole Christmas, about a grumpy creature who tries to ruin the holiday for Whoville. The character returned in later television specials and films, keeping his sneaky grin and laugh familiar to new audiences. This baby version reimagines that laugh in a much younger, higher voice and spread through soundboards, short videos and holiday memes. Creators keep returning to it each winter and beyond because it instantly signals mischief without needing any setup or dialogue.
