"How remarkable! Half tree/half transmission tower, having one of these makes it possible for a monster's happiness to be affected by their "likes" placed anywhere on the island! You should be happy too, since you can now decorate your island however you'd like!"
Decorations inside the Storage Structure and monsters inside the Hotel Structure are still affected by the Unity Tree's powers. However, if all of one decoration type is sold, the monsters will still get sad. An indirect benefit of having a Unity Tree on an island is that you can sell off any duplicate decorations, freeing up the space they occupy.
A Unity Tree does not send Happiness effects between a regular island and its Mirror version. A Mirror Island needs its own Unity Tree, which works only within that island.
This structure cannot be sold or otherwise removed from an island once it has been purchased.
