Elephant homage
When you’re creating a world for a film that is a lot different from ours, then you have to make slight changes when you want to add your Easter Eggs. In the world of Zootopia, there are no people, only animals.
So this cameo is slightly different. We don’t see Anna and Elsa in their usual form visiting the film, but we do find two rather cute tiny elephants dressed up as the popular Frozen sisters, wandering along the street. We’re sure the royal pair would be flattered.
