Well, there are times that LEGO projects astound me. And this is one of those times. Here is a LEGO Muppet-looking hand puppet built by Jason Ruff (aka Dr Mobius.) The hand puppet looks really friendly though I'd keep him away from any Classic Space creations you have lying around. An explanation for that reasoning is contained in this video here.
So check out Jason's creations! If you peruse his Flikr account here you can see has has a number of other great LEGO creations.
