Plush Teddy Bear Centaur on sale here (for about $500, I think). Via.
Also, if you haven't seen it by now, FAO Schwarz is selling a design it yourself Muppet for $90:
You can design and order a Muppet from their website. Irritatingly, the creation tool doesn't show you how your figure looks until you complete the whole thing. Also, you must choose each option, even if, for example, you don't want it to have hair.
*Previously: $10,000 doll house from FAO Schwarz.
*Buy Star Wars Muppet figurines at eBay.
