Synopsis

Egghead and Olga, Queen of the Cossacks, made off with two pounds of radium from the Gotham City Radium Center. They intended to use it in their “Zapping Machine,” hoping to hatch an ancient Neosaurus egg, with a rather ambitious plan: to feed the newborn dinosaur a meal consisting of Batman, Robin, and Batgirl. Remarkably, the machine appeared to be functioning as designed. However, when the egg finally cracked, the baby Neosaurus proved to be far more formidable than they had anticipated.
