Sheriff Callie is the protagonist and the sheriff of Nice and Friendly Corners. Callie is a tomboyish but beautiful calico cat who is always ready to lend a hand. She is charged with making sure the town upholds its reputation for being the friendliest town in the West.
Perhaps Callie's greatest talent is the use of her noodle lasso for show and sport. Because the lasso is magic, it can take the form of other objects like hammers and stairs. In many events, it has saved Callie and the others from trouble. Callie plays her guitar in numerous episodes, and often times sings to accompany it.
Callie is all about helping others, fixing things, and giving advice. Whenever there is a lesson in an episode, she is usually the one to help others see it.
