Stonecutter Premium Items - Which did you buy?

Personally, I bought two and they were well worth it. I would recommend getting Number 51 (the alien) and the pyramid. The pyramid looks great and it will help you get more emblems. The alien actually has tasks, which is awesome. I really like him. Together, they'll cost you 200 donuts. If that's too steep for you right now, I'd go with the alien, just because I really like characters and he's a very unique/unusual one who won't be around forever.
