The Pied Piper from Space - S3.E9

Traveling from a distant corner of the universe, a fleet of unidentified ships head towards Earth to hypnotize all children and gather them to Monument Valley, Arizona. The Super Friends start to take action after the Wonder Twins became hypnotized and a call from the Justice League TroubAlert. After the Super Friends tried to stop the children from entering a spaceship, a UFO arose to destroy a nearby city. Batman and Robin stayed with the children as Superman and Wonder Woman stopped the UFO and the disasters it caused, only to get trapped inside the space craft as it heads to the Anti-Matter Universe. Meanwhile, at the Hall of Justice, the Wonder Twins escape by using hypnotic mind control on Aquaman to release themselves. Batman and Robin arrive back at the Hall of Justice to stop a nearby power source overload and snap Aquaman out of a mindless slumber.
