For Lonny’s Birthday, Ronny wants Hop & Penny to make her the best cake ever! But what is the best cake ever? Hop, Penny & Hoot (who offers to help as well) all have different favorite desserts. Their various attempts wind up overloading the Tastymajig and it breaks down. Eventually they decide to ask Lonny what her favorite cake, and Lonny even helps them make it, which turns out to be an activity that makes her birthday super fun and memorable.

HOP follows a diverse group of best friends who encourage young children to embrace their individuality. Hop, an energetic, sympathetic frog with one leg shorter than the other, guides his endearing and eccentric group of friends in solving kid-friendly situations.
