In the script for the season two She-Ra episode "One To Count On" the role of Sprint was originally assigned to a new Twigget named Sprigget. During production this new character was dropped and Sprint was used in his place. This explains why in the actual episode Sprint's voice is different when compared to his original appearance in the season one episode "A Loss for Words".
