Set includes everything shown in the pictures. It's only missing 2 out of the 4 of the small rock walls. It looks like the whole set could be built without them or you could use these parts to complete your set. Also, one of the sticks is green instead of yellow. Not sure if it is original.
All pieces are in good condition.
The box isn't in great condition, so if you don't need it, I can ship without it and save you on shipping. Just send a message before you buy.
