Orb (Paper Mario: The Origami King)

The Orbs are special items in Paper Mario: The Origami King. They are used to unlock the Sea Tower and are all found on Diamond Island. They are first mentioned by the statue on Bonehead Island mentioning the orbs, the island, and Shangri-Spa. Once Mario and Olivia have entered Diamond Island, another statue congratulates them on finding the Diamond Key but informs them their challenges have just begun. It explains there are three trials on the island, which can be completed in any order. Clearing each trial awards Mario an orb. Olivia sees the orbs as prizes for clearing the trials, and they set out to earn them.

The orb found at the end of each temple corresponds with the trial held at the temple. As such, the Power Orb is found at the Trial of Power, the Wisdom Orb is found at the Trial of Wisdom, and the Courage Orb is found at the Trial of Courage. Once all three trials are conquered, Mario is congratulated again by both the statue and Olivia. However, Olivia soon realizes she does not even know what the orbs are meant for.

As it turns out, each orb must be used to access the Sea Tower on the other side of the ocean. They must each be inserted into the door to slide open the gate, allowing them to enter the tower. The orbs are not seen again after that, and as such no longer have any purpose.
