Challenge of the SuperFriends S01E14 - The Beasts are Coming

After an experimental satellite from Kennedy Space Center falls back to Earth it breaks, releasing deadly radioactive energy. The Super Friends then receive a distress call from the West Coast saying Death Valley is being overrun by giant desert beasts. Wonder Woman and the Wonder Twins stay behind to check the Justice League computer for more information, while the rest of the Super Friends head to Death Valley. At Death Valley they find wreckage and a man who says giant lizards had nearly destroyed the town. As Superman continues to search for the mysterious giant beasts, he stumbles upon some mutated giant earthworms that he must save some teens from. As Aquaman, Batman, and Robin fight the creatures that attacked them, Wonder Woman finds out what happened via the Justice League computer and heads to NASA for more information. As Wonder Woman approaches the location of the downed satellite, the radiation turns her into a giant beast. As the Wonder Twins try to stop Wonder Woman's destruction of a military base, the radiation genetically alters them into giant beasts. Meanwhile, giant earthworms are digging holes into California's coast, which will potentially sink. To save everyone, the Super Friends must stop the creatures and turn them and the "Wonder" heroes back to normal.
