Piscciss is an aquatic planet. It is a large ocean with the only land being the core, which makes up less than 2% of the planet.
Piscciss's liquid atmosphere is held together by an artificial gravity multiplier.
Piscciss first appeared in Deep when Aggregor went to get the second piece of the Map of Infinity, which was disguised as the planet's artificial gravity multiplier. After it was taken, Piscciss started to break apart, but Ben transformed into Goop, gave the planet his Anti-Gravity Projector, causing him to be atomized and reform the planet.
