Synopsis:
Superboy is exposed to Red Kryptonite. This time he is transformed into a monkey and is forced to work for an organ grinder. Lana buys a license for him and gains ownership. She intends to expose Superboy's secret identity, but before she can act a secondary effect of the Red Kryptonite causes Superboy to grow into a giant ape that menaces Smallville.

Miles away, Beppo the Super-Monkey sees Superboy with his super-vision. He comes to fight the super-ape, but is also exposed to the same piece of Red Kryptonite. Beppo changes into a double of Superboy possessing his intelligence too. Beppo then helps control the wild super-ape until the Red Kryptonite wears off. Because he looks like Superboy, he is also able to protect Clark's secret identity from Lana.
