Ben, Gwen, and Kevin are summoned to the aquatic planet Piscciss (Ripjaws’s homeworld) by Magister Pyke, a Plumber who reports that Aggregor has been sighted near the planet’s solid core. Ben and the team pursue Aggregor and reach the planet’s center, learning that the second piece of the Map of Infinity is disguised as a gravitational device which is responsible for holding Piscciss’s liquid atmosphere together. Aggregor steals the piece of the map and flees, causing the planet to come apart; Ben transforms into Goop and uses his antigravity device to replace the map piece, which stabilizes the planet’s atmosphere. While Ben and his team are celebrated by the people of Piscciss for saving their world, they lament that Aggregor has once again escaped from them.
