When we were there in July 2019, it smoked and sparkled. It was awesome. We've gotten it both times we have been there. Again, our last visit was July 2019, but I don't see how Covid would make them stop with the smoke.
We go just to share the chocolate extinction! The last time we got it was December of 2019 and the smoke and sparkles were there. The rest of their food is average at best so we eat lunch or dinner somewhere else and go to TRex just for dessert (side note- they do not give us the 10% DVC or AP discount if we don't order an entree).
