The MOC was built by flambo14 since May 2016.
A witch inside her crooked tower with the cute little steps down to the water.
In fact, there are many creators out there like to build their MOC with this theme, but there are not many that can really create the effect of witch tower. Well of course there are no specific rules on how the witch tower should look like, but the feel to the fans is important. After all flambo14 made it quite well on this MOC.
