Picked up a bag of extra dots and I'd recommend them. Comes with a decent colour selection (though a bag with less pastel/bright colours like dark blue, dark red, and dark green would be much better) an the pieces are useful for tiling.
As for the emojis, I picked up this pack because of the skull (turns out I got 2 which is a bonus) emoji, and was hoping that the diamond and leopard print pieces were in there. I was hoping I wouldn't get the shit emoji, but lo and behold there was 1 in the bag. At least the bags have clear windows so it isn't a blind bag.
