The frame that used to hold the Sacred Stone

The Sacred Stone was a "magical" stone that was kept in the frame of Adam's mailbox. The boys used to pretend that it had magical powers and if they touched it they would get really pumped up. One time, the stone got stuck in the mailbox frame. It could not be removed by normal means, and The Sacred Device was the only thing that could remove it.

Currently, its whereabouts are unknown.
