The term "Zootennial" was first used for the Zootennial Stadium, a prominent location only present in an early script for the film. The stadium hosted a world's fair, and was the original location for Gazelle's concert.
Description[]
The colors used to promote the event are green and yellow. For the celebration, Savanna Central is shown to be decorated with banners for the Zootennial. A parade with a marching band is organized, and the Lynxley family contribute by hosting the Zootennial Gala in Tundratown.
Judy and Nick later go undercover at the gala to apprehend Gary De'Snake, who plans to steal an antique journal detailing the weather walls, purportedly written by Ebenezer, which is set to be displayed there to clear the bad reputation that snakes have in Zootopia. When Judy (alongside a reluctant Nick) decides to trust Gary, the three of them flee the gala and go on the run.
