I think it's ironic that so many people are having trouble locating the Muppet Labs playset.
Diamond Comic distributors actually ordered way more playsets from Palisades than they did Wave 1 figures.
Diamond's cases are numbered, and the wave 1 case I got was numbered out of 417 cases Diamond ordered from Palisades, so, at two per case, comic shops only got 834 Dr. Bunsen Honeydew figures.
In contrast, my local comic retailer's case of Muppet Labs playsets was numbered out of 556 cases Diamond ordered from Palisades, so at six playsets per case, comic shops got 3336 Beaker/Muppet Labs playsets.
Diamond's order numbers can't be the norm for the other retailers, otherwise there would be a heckuva lot of playsets with no Bunsen's available to make an appearance in the lab.
