Jack is the protagonist of Jack's Big Music Show.
Jack is a super swell preschooler and the star of the show. Every day Jack gets to spend his own special time in his favorite place in the world: his backyard clubhouse. It's here that Jack meets up with his dog Mel and his best friend Mary and he gets to do what he loves best: make music, sing, dance, and have a great time! Jack's interest in learning all kinds of music leads him to discover melodies in the most unpredictable places, like finding rhythms in raindrops and musical tunes from tiny bugs. To Jack, music is the greatest. There's always something unpredictable going on in the clubhouse and Jack has a way of using music to save the day.
Jack is blue with a black nose. He wears red sneakers, brown pants and an orange and red shirt. His hair is green.
Jack appears in every episode of Jack's Big Music Show. He debuted in "Little Bad Wolf" and was last seen in "Silly Show."
