I just noticed this. The tutani plushies are randomly missing Sun and Marsh colors. Not a big deal or anything, but kind of a bummer since I wanted a Sun Tutani Plushie for a TC.

Which leads me to wonder: is this a common thing spanning across the various species plushies?

I think it is a common thing. For example, while looking at the Kumos plushies on the site, I've noticed that there is no marsh Kumos plushie. Plushies are usually in basic colors and most of the basic colors are covered, though non-basic colors such as nightmare or steamworks are rarely seen in plushies.

I would love to see some steamwork plushies o.o I do hope they'll make one for next year's masquerade XD off to make item suggestion

This seems more like a suggestion for some new items, so I'll pop this over to that forum. c:
