I remember now it was Allears that had said about it leaving. But, I texted my friend who was just there and asked her about it, this is her reply to me this morning:
"We went all three magic kingdom days to try and get one for the girls to share, every day between 10 & 10:30. Each day we were told they were no longer serving them. I didn't know if that meant they were off the menu or what, could be that they were just done serving for the day. I don't know. One of the girls lost her band....ok, I lost her band.....and we had to go to the guest relations office thing, and I asked them about it. I was told it was a supply chain issue and they can't guarantee that they will serve them that day which si why it's not on the menu. The lady told me they usually have it, but once they're gone they're gone. I don't know, my girls were really sad about it. You might have better luck when you go"
So that's what I know, they just got back a couple of days ago, so I guess if you want one get there early.
