Build your own custom Muppet and FAO Schwartz will send it your way for $90. Too pricey for me, but fun to play with in concept.
I want this super cool looking Edison Cylinder kit. I say "looking" because I can't read a word of the text since it is all in Japanese. They seem to have a much larger adult invention community than here in the US. For only $35.56 it looks like a bargain.
