Prisoners of Sleep / An Unexpected Treasure / The Malusian Blob - S7.E6

Prisoners of Sleep: While investigating a strange electrified spiked metal pod, Superman and Batman unwittingly unleash the cloud-like prisoner inside (named Sleep), and are then trapped in a dream world.

An Unexpected Treasure: Two teenagers discover an ancient warship buried underneath the desert sands and they take off in it. The Wonder Twins and Gleek attempt to rescue the teens and they ultimately seek the help of Hawkman and Hawkgirl. The Malusian Blob: Space shuttle astronauts unwittingly load an alien chemical blob into their cargo bay (assuming it to be space junk). The blob starts eating metal and the astronauts call for help. Batman, Robin and Black Vulcan arrive and rescue the astronauts. Assuming the blob burned up in the atmosphere, they return to Earth, but then the blob reappears and after some failed attempts, they figure out that the substance may have an unstable reaction to sugar.
