I've honestly only ever finished two goals...I usually never do them because I don't feel like I will finish it, or I don't like it.
I wish TeamLava would let us have every oven without needing to complete goals to get them. I want the gems..but I don't want to do these goals with silly themes. I don't want St. Patricks Day stuff in my bakery, nor do I want pirate ships in it! It sucks..
