A giant vulture captures a Dorgyte and Dorno spots it and calls the others to rescue it. Zok beats the vulture. They escort the Dorgyte through the Stone Forest to safety, but on their return are ambushed by a spike-shooting caterpillar, an armadillo-like creature, and electricity-shooting beetles. The Herculoids prove triumphant and get back to their own valley.
