I really love the Jumping Pumpkin. And I love it is possible to collect fragments to them. Over time, they can replace my blacksmiths, even when it will take long time.
I do dislike, that gold liga (star baker) is only way to get a building that gives fragments to golden upgrade. The level one of the building in silver liga is better than nothing as the Rusty Vineyard do give fragments to Jumping Pumpkin.
But yes, it will cost RL cash and diamond, however the RL cash for the ekstra Fall prices will help, even without diamond
