Super Friends

The Case of the Shrinking Superfriends (8x7)

Air date: Sep 29, 1984

Lex Luthor invents a shrinking ray and uses it on the Hall of Justice. The older members of the Justice League had earlier flown off to fight a mission in space... leaving behind the junior members like Robin, The Wonder Twins and Gleek, and Firestorm. Luthor succeeds in shrinking the Hall of Justice and it's up to the now miniature Superfriends to save the day before the senior members of the group return from space.
