Synopsis:
Supergirl, having been given immunity to Kryptonite by Mxyzptlk, decides to locate and destroy several Red Kryptonite meteors. Her immunity does not extend to Red Kryptonite however, and she begins to undergo several transformations.

First her body begins to expand while at a carnival with Dick Malverne. She disguises herself as a giant balloon until the effect passes. Next while at a movie, she is transformed into a wolf-girl, inspiring a screen writer to come up with a new movie idea. Finally, she shrinks to tiny size and enters Dick’s father’s bloodstream to defeat a life-threatening disease.

Having been affected by six pieces of Kryptonite, Supergirl knows she will undergo three more startling changes.
