Keeping in Disney’s tradition of scattering Easter eggs throughout its films, the upcoming Zootopia has a big shout-out to Frozen — and we’re not just talking about the voice casting of Kristen Bell.
One of the latest images to be released from the animated film reveals a scene in Tundratown, the icy district of the animal kingdom’s city. A family of elephants is spotted in the lower left-hand corner, and closer examination reveals the two children to be wearing the costumes worn by Elsa (voiced by Idina Menzel) and Anna (Bell’s character) in Frozen.
