Gem

A Gem is an item given to signify the completion of a realm. Every zone except Royalton Racing Complex offers a Gem upon completion. Gems are able to be viewed in the Crib's Trophy Room.

List of Gems
Warning: Some spoilers are ahead!
 * The original four zones (Funkeystown, Magma Gorge, Kelpsy Basin, and Laputta Station) each offer their own individual Gem, described in-game as the power sources for the portals.
