"A Day in the Ocean"
The supervolcano of Yellowstone releases a huge amount of smoke and ashes; so much that it hides the Sun. When temperatures start going down drastically, and a lot of animals start perishing from the cold or the toxins in the air, Fabian, P.T. and Josh must both find a way to survive and pray so this is the worst part. Meanwhile, elsewhere, Randy takes advantage of the confusion and darkness to escape the lag-tar prison.
Just when the disaster is over, an adult chickencorz is savagely killed and eaten by an unknown beast, who turns out to be Cris possessed by Laggo.
