My kids love Zootopia, and honestly I got really interested in how the world works. A city built for every size of animal. A giant weather wall keeping Tundratown frozen right next to the desert. A whole mouse-sized neighborhood tucked inside the city. I kept wanting to just walk around in it. So I asked AI to build it. Two days later it's a real game you can explore. Every district from both movies, and you turn into whoever lives there. A giraffe downtown. A mouse in Little Rodentia riding the hamster tubes. A polar bear in Tundratown. A bat in the cave city underground. You can take the train out to Bunnyburrow, ride the sky-tram, swim through the water tubes, hunt for pawpsicles. The part that still gets me: it built every 3D model itself. No asset store, nothing bought. It wrote code that drives Blender to make the buildings, the animals, the trains. Hundreds of them. Then it playtested its own game. It drove a browser, took screenshots from the player's point of view, and caught its own mistakes, like a tower standing right where you walk in. My job was give the starting prompt and the idea with some links to research sites and reddit, it ran overnight. I can't wait to watch my kids run around in it.
