Lugush gym?

I was un aware of this did they do this with all the whacking day items? Do they cost donuts?

It used to be a limited time only, but on the second update of WD they made it a permanent.

Almost all of the WD buildings prizes can be bought with donuts now and are not. A limited time offer

I'm sort of jealous of all the people with limited time exclusive items. Now I just look like a cash shop junkie.
