Lemme tell you this.. I got the Sababa medium sized Red last last minute... when KB was going under, just before they cleared out all the good stuff. I managed to snag the 12" Wembely with the DVD for about 7 or 8 bucks (forget exactly) and I never got the chance to go back and get the other 2... though Wembely was the one I wanted the most (never managed to get the Hasbro Softee version of him... I got Boober, though).
Oh, and to answer someone's question from a bit ago, yes... there was indeed a Red and a Gobo under 3 figure (Gobo held a carrot for some reason, Red had the more appropriate radish... I kinda like them over the cars) but I only found Red at the comics store... I definitely would have got both if they had them. I found a ..well, I guess rare still in package under 3 Plucky Duck at the same place, but not Gobo. No one really asked for the under 3's, and I wonder what the rarity of them is.
Now, the Doozer in the McD's kid's meal, according to Muppet Wiki was test market stuff... they had one with 2 generic Doozers, one with Cotterpin... but they never made it nationally, and I'd stand to say that no one ever actually seen one of either of them.
