With Pleo, you can expand your family with a pet from prehistoric times. The Pleo is a one-week-old dinosaur that will quickly grow to become one of the most fun and exciting members of your family. This amazing robotic marvel not only moves organically, explores its environment on its own, and interacts with you, but it also expresses emotions based on its life experiences. The Senario Pleo begins life as a newly-hatched baby Camarasaurus, and from the moment he starts moving his individuality begins. Pleo doesn't simply do what he is told; he also develops his own unique personality, moods, and habits that are shaped by the time and experiences he shares with you. The Pleo can go from happy and curious to scared and surprised, and from playful and lively to sad and vexed, depending on a wealth of influences. From hatchling through infant, and all the way through his juvenile stages, Pleo will grow up and change in personality and understanding.
