ha, love the effect of the translucent lil critter and the carbonation going on inside of it, but why not a birch beer bottle next to it to make it "somewhat" in the realm of understandability. Still, really sweet idea!
They mentioned birch beer because it's a chipmunk you goof.
anyways, I LOVE this. without the birch beer or anything. the first thing I thought was root beer because the colours kind of reminded me of A&W. Great job :D
