Synopsis:
Superboy encounters some Red Kryptonite in a mine shaft, and it appears to turn him into a simpleton. He repeatedly makes mistakes using his powers, causing problems for the residents of Smallville. Two crooks try to take advantage of Superboy’s stupidity, but he traps them. He was merely using the dumb act as a ruse to find the boss of a narcotics ring. The Red Kryptonite actually caused Superboy to grow a sixth finger on each hand.
