Fella and the Andros guardian followed through the gate, meeting immediatly with Lemmy, gatekeeper of the Andros gate, and another Andros guardian. Lemmy tried to help Fella stop oil again, but the oil just kept its travel towards the Prison of Andros, where Tritannus absorded its powers and become a monster. He attacked the prison guards, turning them into muted monsters. Fella and Lemmy tried to go seek for help, but Tritannus trapped them and absords their powers and haves an idea of absording powers from all Selkies in order to travel into Infinite Ocean.

Fella and Lemmy tells King Neptune about this and are frightened by his angry reaction.
