Wizbit was a bizarre childrens TV show from 1986 starring Paul Daniels (who also sang the theme tune), Debbie McGee a talking yellow wizard's hat and a big white talking rabbit.
The yellow wizard's hat was called Wizbit and he came to visit earth from the planet WOW (World of Wizards). Whilst on earth, in a place called Puzzleopolous, Wizbit would hang around with the big rabbit, and would solve puzzles at the Puzzle Gate which would only open if you solved the puzzle. The other inhabitants of Puzzleopolous included some decks of cards and some foam balls.
Very strange program but rather compelling nonetheless.
