How Skibidi Toilet mobile game grows

Reached the Skibidi Toilet creator (DaFuq!?Boom!) early, at ~5M subscribers, and built a game with him on a 50/50 split. His audience followed a saga of characters but could only watch it; the game let them enter that world. He made one YouTube Shorts promotion; word of mouth did the rest. Good fits have an inside joke or a universe the game can extend, and comments that show a real community rather than follower count.
