When Ray's memories are stolen by the Choten, the kids travel into the depths of the Water Realm to recover them. With "Reef Prince" Gargle as their guide, all goes as planned until they're charged with stealing a prized artifact.

To protect Bob's Quillspike family from a massive attacking creature, the kids go to the Nature Realm and duel in an arena competition to win the Shield of Unity - an artifact that compels all other tribes to help whichever tribe possesses it.

Wanting to teach Carny a lesson, Ray and Bob find themselves stuck in the Fire Civilization with the bully, and they must work together to survive long enough to make it back home.

Princess Sasha returns, sent by the Light Civilization to study humans. In disguise, she attends school with our heroes, and is introduced to mean attitudes, cyber-bullies, and powerful emotions - all of which make her question humanity.

Sasha sends a message to Gabe that her home is under attack. Reaching the Light Civilization, the kids find Alakshmi, Fingers and Heller attacking Sasha's fortress in search of the final powerful Artifact - and they will stop at nothing to find it.
