Flipside Tower

Flipside Tower is a towering building in the center of Flipside. Akwardly, inside Flipside Tower, the sky can be seen and there seems to be no walls or any ceiling for that matter. Mario meets Merlon in Flipside Tower and uses Flipside Tower for its purpose.

Flipside Tower's purpose is to provide a transporting system that warps people to other worlds via its Pure Heart Doorways, powered by Pure Hearts that Mario finds along his journey.
