How to Hatch a Dinosaur

Summary

Egghead and Olga, Queen of the Cossacks, steal two pounds of Radium from the Gotham City Radium Center. Using it in their "Zapping Machine," they attempt to hatch an ancient Neosaurus egg, planning to feed the baby dinosaur a meal of Batman, Robin, and Batgirl. Surprisingly, the machine seems to be working. But when the egg cracks, the baby Neosaurus is more than they can handle.
