With the aeroglyer in submarine mode, the team travels leagues under the ocean to find next map piece. On the run in the forest, Nar Est gets a ride with a carriage of Funkfangs. Under the sea, the heroes come upon a massive celebration called Boiling Crab. Around a crevass, Larry the Lantern Fish warns the only creature able to survive below is the LAVOCTOPUS. Meanwhile, Nar Est notices that baby Funkfang is wearing an amber crystal and steals it. He goes into the woods and summons the Dark Champion. Back at Boiling Crab, Chompsky has retrofitted the Golden Crab into a mech suit, which they pilot as a team. They go into the abyss and distract the Lavoctopus with shiny treasure while they try to reclaim the map piece. Niko goes into a trance, seeing the dark and light entwine, before finally snapping out of it. Niko and Lyra work together to unseal the lava vent and realize that the Lavoctopus wasn't evil so much as trapped. With the Lavoctopus free and swimming through the new streams of lava, the team hops back into the submarine and head for the surface. Far off, D.C. hears Nar Est's summons. He turns and marches away, back in the game.
