Who would say no to a treehouse? I am absolutely sure that everyone would love to have one. It is the perfect place to spend your time. Ice Princess. Ana, Brave Princess and Mermaid Princess decided to build their own shared tree house and every princess has her own room. Now all it's left to do is to decorate the rooms. Help them out by choosing a cute bed, a carpet, decorations on the wall and a lovely sofa with a coffee table. Once done, help the girls dress up in something cute and cozy to hang out in the tree house. Have fun!
