Challengers of the Unknown #47

In "The Sinister Sponge," the Challengers of the Unknown encounter Miklos, a man transformed into a living sponge after a diving accident, as he struggles with his strange new form. When his neighbor Stacy promises a cure, Miklos sets out to find the money—only to find himself drawn into a crime spree that drains color, sound, and even the Challs' strength, all while the truth about Stacy begins to unravel.

In "The Terrors of Mr. Tic-Tac-Toe," the Challengers of the Unknown find themselves stranded in the desert after a forced landing, only to be ensnared by the eerie Mr. Tic-Tac-Toe and his silent accomplice Herbert. As the team is scattered and trapped in a surreal game of deadly proportions, the line between puzzle and peril blurs—until Prof must outwit the twisted game master with a clever swap that could turn the tide.
