Wyatt Griswold is an American voice actor. He is the original voice of Rusty Spokes. He was replaced by Owen Rivera-Babbey starting with "Schooled!" due to focusing on his carrier.[citation needed]
Griswold has voiced Rusty the longest out of all of his voice actors, having voiced him in many of his speaking appearances from Seasons 1 to 4 over the course of over 4 years.
Griswold couldn't reprise the role of Rusty, due to focusing on his carrier. It's unknown, yet unlikely, that he'll reprise the role.
