Nellie Sue, who fancies herself a real cowgirl, wants a horse for her birthday, but she discovers that a brand new bicycle--her first--takes almost as much taming as a filly.

"Rodeo Red and her hound dog, Rusty, are happy as can be until Side Swiping Slim comes to town and starts stirring up trouble for them, but when Slim steals Rusty, Red will do anything to get him back--even give up the birthday gift her Aunt Sal, a city slicker, sent." -- Verso.

Cocoa the horse herds the cows with Cowgirl Kate, helps her practice her roping skills, and wishes he could wear boots instead of horseshoes.
