As a fellow collector of HTTYD I thought I would share this,
sta.sh/21hg76mqepie , I was looking around at a bunch of targets on my way home from orlando, and I found them at one of them, and never saw these variations, one is basically the white Night Light(with one my friend grabbed for me for comparison) with blue markings, I guess like some of the toothless figures have, it was even in the same colored egg as the white one. And the other is a new toothless egg with the same kind of blue markings as well as the same kind of fabric that the Night Lights have, as well as different eyes from the rest of them. Also in the same box I found these 2 eggs, I saw the purple stormfly I think, but either way I figured I would inform you they have new egg plushies out and that you should be on the lookout for them.
I am also starting to see the green egged Night Light start to pop up a bit on ebay so fingers crossed I can find them or my friend can.
