Love these stone snakes. They have these all over the place, inside, outside... There is something fascinating with this life size witch doll with her crocodile footstool... Maybe a witch collection could be interesting as well?
Suffragettes might be another interesting collection for "my" "house on the rock" :-)
There is also "Granma Brisbey's Bottle Castle", which to me feels very chaotic... The following bottle buildings look much nicer :-D
