There is also a tiny bear-thing and a deer-thing on the front page that you can get in kit form. The Super Gem dolls are the ones most people seem to want, and it's nice that Soom now offers boy Dias as an option since I think the "Boy Dias" outnumber the girl Dias. The kits are all the "Steady Sellers" from the sidebar, there are no monthly doll re-releases in there, though I always check. :)
Here's the page for the kits--to select the doll you want, pull down the drop-down menu on the top.
