The misadventures of two modern-day Stone Age families, the Flintstones and the Rubbles.
Pinky and Brain are genetically enhanced laboratory mice who reside in a cage in the Acme Labs research facility. Brain is self-centered and scheming; Pinky is good-natured but feebleminded. In each episode, Brain devises a new plan to take over the world, which ultimately ends in failure, usually due to Pinky's idiocy, the impossibility of Brain's plan, Brain's own arrogance, or just circumstances beyond their control.
This time, while building a hideaway in their new home of the Great Valley, Littlefoot and the gang rescue a mysterious egg from two scheming egg-nappers and make a starling surprise - and new friend - when the egg hatches.
