Book Worm
I borrowed some worm-design from a children’s show which aired in Australia from the 90s until, I think, the early 2000s. It was called ‘The Book Place’ and the star was a book worm puppet who would assist the cast in reading recently published children’s books to the audience. I remember it as a good show and you can see the worm in the end of an episode here: (he didn’t normally wear a hat)
