Synopsis for Superman and Supergirl: "Spawn of the Unknown"
When the experimental plant-seeds of Prof. Bruno, who is operating in Africa, run wild in an extinct volcano crater, Superman is called in by an old game keeper friend. The game keeper tells Superman the seeds have turned animals into plants, and, when they see a plant-creature with Supergirl's costume, Superman is convinced his cousin has become a victim. But the real Supergirl appears later, and says that the "Supergirl" tree--like a "Superman" tree which sprouts not long after--is only a plant. Professor Bruno's plants imitate the life forms around them. Superman and Supergirl take the volcano crater to a remote planet, but save the Supergirl and Superman trees for the Fortress of Solitude.
