The article is a bit long, but it's worth the time to read it. Up until now, the weirdest story I've ever heard was that of the "Hopkinsville Goblins," but "All Colors Sam" takes the cake. What is he? Alien? Ghost? Robot? Cryptoid? Ultraterrestrial? Figment of a little girl's imagination?
The "Astonishing Legends" podcast guys did a really entertaining show on the "Ghost Clown," I highly recommend it. I'm going to do some research into it as well, including asking the local police (on the Isle of Wight) if there were any disappearances, especially of children, around the time Sam was reported.
