You and your siblings all have dopplegangers here. Seriously, there's a bagger at the local grocery store who looks almost exactly like you, and regulars at the coffeeshop who are dead ringers for your sibs. It's a little weird.

I see what you meant in that comment about your sister being very expressive, too :D

I think those Exotic Sands things have been sold at the Pacific Science Center gift shop, at least at times. Or maybe somewhere in the Pike Place Market. Some of the pictures on the website and the general concept look really familiar.
