Fan Casting Billy, Goat and Gruff in Woody's Roundup

Billy, Goat and Gruff are three members Little Bo Peep's beloved flock of sheep. They're also adoptive sisters to the latest addition to the flock, Blackie the black sheep, who's their brother. Their other animal friends include Slinky the dog, Sox the cat and Bullseye the horse. They have a habit of running away sometimes, but thankfully Woody always manages to bring them back home somehow. They also like munching on grass, going for walks with Bo Peep and everything else that sheep like to do. Here's how you could tell them apart. Billy is the oldest and also the leader of the flock. Goat is the middle child and is a little shy. Gruff is one of the younger sheep and is the toughest one. Even though they do run away sometimes, they still love Bo very much and wouldn't know what to do without her.
