Episode Title:
The Purple Moss.
Episode Description:
Fed by rays from a hovering mental sphere, a suffocating purple moss is spreading over the countryside. Birdman must get inside the sphere to confront Xandu, who is scheming to take over the Earth for the planet Moger, but he turns out to be a trick image. Birdman is immobilized by a centrifugal force machine and a strange spray and dumped outside the craft; he recharges his strength and goes after Xandu, neatly arranging to send the enemy out into space in endless orbit, locked there by his own harmful ray.
