There are players who believe these items are too expensive and require too much material to develop them;
there are players that have tried them and put them in store or sold them after a while
and there are players who love them:
Upgradable decorations such as the School of Magic, the Snowman and the Tree of Light.

Perhaps we can make you enthusiastic (again) about developing these decorations by sharing how you can place them in your Town or Zoo.
I would like to call the 'Proud owners of ...' to share their arrangements in their towns with these puzzle decorations.
Did you put them stand-alone or did you combine them with other decorations, factories and community buildings to create a beautiful arrangement?
Hereby I invite you to share the screenshot (s) of your Upgradable decorations with the members of this Forum. You can find more about sharing screenshots
here.
