Priscilla is voiced by Kristen Bell, who also voices Anna in Frozen. This is because when casting director Jamie Sparer Roberts watched an interview with Kristen, she explained her love of sloths and how she had a meltdown of joy about getting to meet a sloth for her birthday. They asked her if she would do two words of dialogue if it was a sloth, and she answered in two to three minutes, "Yes." Roberts jokes, "It was the quickest deal ever made in Hollywood."
Role in the film
During Judy Hopps and Nick Wilde's visit to the Zootopia DMV, they enlist Flash's help in tracking down a vehicle. However, while Flash is inputting the vehicle's license plate, Nick distracts Flash with a joke, much to Judy's dismay. Flash then retells the joke to Priscilla, angering Judy even further.
During the time of Gazelle's performance, Priscilla and Flash are seen literally slow dancing as they hold paws.
