Plot

Thelma is a small farm pony who dreams of becoming a famous musician alongside her band mates Otis the donkey and Reggie the llama, who form a band called The Rusty Buckets. After humiliating herself at an audition that would have guaranteed them a spot in the singing showcase event SparklePalooza, a clumsy truck driver accidentally drenches Thelma, while wearing a carrot on her forehead, in glitter and pink paint, giving her the appearance of a unicorn. Her appearance attracts a small crowd to her farm and she seizes this opportunity to sing in front of them. Despite Otis' objections of lying to people in favor of performing as their true selves, Thelma decides to stick with her facade.
