I was so excited to visit FAO Schwarz when I heard about their new "make your own" Muppet station. They've been available for several months now in the store and online.
If you're ever in the New York area and are a fellow fan of the muppets, you have to stop by FAO; if not to buy then at least to see them in person. They don't have any of the famous muppets on display or available to make but the Whatnots are just as amazing. I know it sounds weird, but when you see them it's like seeing a celebrity. So cool.
