An eBay user by the name of NatNerd123123 has just listed the original Jim Henson Creature Shop Baby Master Splinter puppet used in Teenage Mutant Ninja Turtles 1 from 1990!! The puppet was used in the Ninja Turtles origin story scene when they are first talking to April:

Very cool to see it with a bit of a description on how it works. It's been decades since this movie came out and I assumed that most of the props were nonexistent. This Master Splinter prop however looks like it's in prime condition! I really wish this was on my shelf.
