I guess it's heresy to say that a robot dinosaur can be cute, but definitely is at times. If you put your Roboraptor in free roam mode while he is in Playful Mode, he'll roam around for a few minutes, and then he'll stop and do what is becoming known as the Happy Dino Dance. He stands in place for a bit, obviously contented with himself, and makes pupply like chuffing noises while he dances and wiggles in place.
