Jigsaw (partially found children's TV series; 1979-1984)
Jigsaw was a British children's show that aired on BBC from 1979 to 1984 with a total of 45 episodes in six seasons. The show featured elements of puzzle solving as well as various skits and had several hosts/presenters, including Jig, Dot, Hector the Hedgehog, and Noseybonk, who is likely the most well-known character from the show thanks to his infamous mask (that has been used in multiple creepypastas) and YouTuber Ashens' show, Noseybonk Returns, which featured the character doing various evil things. Despite the show's mild infamy, nearly all of the show's footage is not available online. A list of found episodes/clips can be viewed below.
