The collection isn't officially released until 1st November, but I obsessively check BeautyBay.com (where I get many of my polishes) for new nail colours and I got lucky last Thursday - The Muppets Collection is on there already! I wanted them all, but being somewhat insolvent at the moment I had to limit myself to three. I chose Rainbow Connection, Gone Gonzo!, and Excuse Moi!
Top to bottom: Rainbow Connection & Gone Gonzo! & Excuse Moi!
Rainbow Connection is the one that seems to be creating the most buzz - and in fact, I just went back onto BeautyBay.com and it's not on there anymore, so it must have sold out already (thank you, nail polish gods, for letting me nab a bottle!). It's a clear polish with multi-sized hexagonal glitter in silver, green, yellow, blue, orange, and pink. It looks to be a close, if not perfect, dupe of Deborah Lippmann's Happy Birthday, although I don't actually have Happy Birthday in order to do a proper comparison.
The polishes haven't arrived yet for me to try them out, but fingers crossed they'll be in the post tomorrow.
