Most of the other puppets on this list are creepy by being cheaply slapped together. I cannot say the same for that guy. He's too well made, and Uncanney Valley is the reason why he looks creepy. He looks like a real human with... uh... whatever the Elephant Man had, I guess? I guess Brazil likes ugly puppets or something.
I remember some Portuguese language show with puppets doing a parody news show of some sort (their version of Telechat, but with human puppets) someone made me watch that made it hard to sleep that night. They were more cartoonish, but suffered greatly from Uncanney Valley.
