Pleo is the Robot Dino toys from Ugobe of Emeryville, California, but is nothing robotic like you ever see.
It will fall asleep, and when you touch its back, it wake up and give you a tired look. Sometimes he lean against the table leg and howl, sometimes he do things to try getting your attention, he response to what you say, and there are thousand of other possibilities. (Link)
According to the designer Caleb Chung, Pleo is not a robot, it is a designed life form.
