Troll Dolls are toys that date back to 1959. They were first made in Denmark by a Danish woodcutter, Thomas Dam. The original troll doll was carved as a Christmas gift for Dam’s daughter, Lila. When the kids in town saw the doll, they wanted one. too, and the company “Dam Things” was born. The dolls were made from plastic instead of wood, and were called “Good Luck Trolls”.
Still popular today, the Troll dolls are being used as planters, often for succulents. They are so cute!
I don’t know for sure how they are made, but my guess is that you would remove the hair, and maybe remove the plastic base of the hair, so there would be more room for the potting soil. Then add your soil, plants and water.
The larger sized troll dolls could hold a larger plant, as in this picture:
