I *think* we saw some pygmy puffs in one of the shops outside WWOHP, just not sure which one. I say *I think* because my ds looked at a purple one and wherever we were was not cramped or crowded at all.
I didn't see any of the beverages outside of WWOHP. A few of the candies, but that is all. Hopefully someone else knows more that I do.
They have pink pigmy puffs at the Universal shop at the airport (I saw them earlier this month when we were flying back home). However, no beverages of any sort and a limited selection of sweets. Hope this helps!
We went to wdw in Feb and my twin 8yo daughters highlight of the trip was the universal store at the airport!! They love HP one bought a pygmy puff and one bought the phoenix(faux?)
