Slodge is a very rare substance that can only be found on a few planets in The Jurassic Quadrant, including the triceratops planet Aggadon. It appears smelly and bland on the outside, but it is very valuable because it is a great building tool; it can become either a liquid or a solid. This unique property caused Tonka, Marvin, and their band of mammoths to come to Aggadon and plot to destroy the planet. However, Chas and Gipsy saved Aggadon by causing their giant wrecking ball to knock their Dungdozer Prime out of orbit.
