Ep 7. Don't Feed the Animals

When Scooby and Shaggy learn that Dr. Phibes is planning to mow down the rain forest to harvest a plant that he believes will make him immortal, the two travel across the world to save the planet. After befriending a pack of rare jungle marmosets and repeatedly fending off a pair of hapless poachers hired by Phibes, Scooby and Shaggy set out to shut down Phibes' automated bulldozers before they destroy the forest. With the help of the marmosets, who eat a variety of new, improved Scooby Snacks (and give themselves superpowers), Scooby and Shaggy turn the bulldozers on Phibes' own jungle lair, leveling it and saving the rain forest.
