The sculpts are strong, the paint work is simple but tight, and there's a nice variety of materials - check out the metal harness handle!
The bad news you won't find these in any stores except eBay. The good news is you can order them from the UK - there's a site called The Prezzy Shop that sells this figurine (along with others from the show). You can buy Pickles for about $14.00 U.S. + shipping. If that doesn't work, try aadrmarket.com's Creature Comforts shop, which has it for $10.00 + shipping.
