They look like generic kid's puppet characters to me. Nothing remotely as creepy as some of the other things I've seen.This is how creepy Scooter and Miss Etta are.
I'm also going to say Bloopy's Buddies. Other than the clear and obvious follow the leader of Barney-oid characters that they had in the 90's, this one's inexcusable for one reason. Johnathan Winters's comedic genius is absolutely wasted here. There were a lot of kids' shows that he could have been in that were far superior. He's pretty much the highlight of the series, but he's been in far better things that really exhibit his talents.
