The Halloween Blocks is a Classic pack which needs 25 Gems to obtain the item. Originally around October 2011, it could be purchased with about 1500 Energy. Ever since November 2011, this pack has always costed Gems.
- Even though there are three smileys that are Halloween related as well as released at around the same time, the Halloween Blocks pack, when purchased alone, does not include those three smileys; They have to be bought individually.
- The two brick slope backgrounds used to be decorations, but were changed to backgrounds soon before the pack was released.
