Episode Title:
Plague of Madness.
Episode Description:
An Argentinosaurus is infected with a flesh-eating virus by a diseased Parasaurolophus, transforming it into a zombie-like state and compelling it to decimate its herd. Spear and Fang stumble across the devastated nesting grounds and become the crazed sauropod's next target. Running for their lives, the duo trick the behemoth over a cliff and into a narrow ravine before finally escaping with their lives by making a mad dash across a lava field. The sauropod's massive weight makes it fall into the magma, which incinerates it as Spear and Fang observe its final agonizing moments.
