A few new big figs have been released at the Disneyland Resort. Released just before Christmas is Stitch dressed as Santa, with a bag of toys and holding an ornament. Here's the link: http://www.colddeadfish.net/images/DLR/santastitchbf.jpg. Price is $150.
Also recently released is a big fig of Kermit the Frog. There's a wind-up key that enables the figurine to play "Rainbow Connection". The fireflies behind Kermit also light up. Kermit is flocked so that he's fuzzy to the touch. Here's the link: http://www.colddeadfish.net/images/DLR/kermitbf.jpg. Price is $150.
A new Tink big fig has also been released, with her kneeling inside a crown. Here's the link: http://www.colddeadfish.net/images/DLR/tinkcrownbf.jpg. I believe the price is also $150, but I'm not positive on that.
Big figs are generally available at Disneyana in Disneyland, Off the Page in DCA and at the World of Disney.
