Available in dream locations:
The tree house is where you can create all kinds of artsy items which will help you get those all important fantasies. Fantasies are the basis for everything you do in Dreamfields as you need them to carry out tasks. Having the Tree House is basically a way to ensure you never run too low on Fantasies again and you can keep churning them out at around 45 every 3 hours. The Tree house is quite expensive to buy at 90 Lunar Crystals but it is worth it, in addition it looks very nice indeed, adding a playful, warm and fantasy filled structure to your dream.
Personally I disagree on whether it's worth the cost.
