This is just a little Sandcastle I decided to build one day. It has a drawbridge, a whole defense system, little dungeon and a roller coaster at the end with a bit of a twist :D. It took me about a week to build and it is my work I didn't copy it from anyone else. I hope you like it:).

Oh and some info... make sure you try out the rollercoaster! And the dungeon was kind of hidden so umm if you can't find it then go to the kitchen in the castle there should be a trapdoor somewhere.
