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
Not much is known about Priscilla, but she knows Flash, as she is working in the Department of Mammal Vehicles. They seem to get along well, and during the time of Gazelle's performance, she and Flash are seen literally slow dancing.
