Adventure Time. She was also the voice of Slippy Napkins in Bravest Warriors.
Polly was cast in the show by the creator
Pen Ward, who was from the same area in San Antonio, Texas.
“She had a wonderful and unmistakeable voice and was always a joy to have in recording sessions. Polly Lou really liked playing [Tree Trunks] and she’ll be sorely missed,”
Adventure Time showrunner
