In "Superman's Treasure Hoard," Superman’s sudden obsession with amassing a vast hoard of gold, diamonds, and pearls leaves Lois Lane stunned—especially when he seals it behind a steel door to lure a thief. With the cave’s location now exposed, he sets a clever trap for the crook who stole an experimental atomic cutting torch, turning his unexpected wealth into a test of cunning.

In "The Tom Thumb Tommy Tomorrow," Tommy and Brent stumble upon a forgotten desert planet once home to a vanished advanced society. After bringing back a mysterious machine, Tommy volunteers to test its effects—only to begin shrinking, eventually meeting the planet’s last survivors, who had chosen to reduce themselves to survive. Now living in the Planeteers’ refrigerator, their new world is as strange as the one they left behind.
