Filipa has always wanted to soar above the clouds, so she decides to build a flying machine. She tries several different designs, but none of them manage to get off the ground. She’s about to throw in the towel when Hop tells about a similar experience he had building the Diner’s slide, and how he persisted and eventually succeeded. Filipa decides to keep at it and then, with some inspiration from some birds outside her window learning to fly, she builds the machine and flies.

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.
