This useful metal pal is a replica of celebrity robot R2-D2. He obeys more than 40 voice commands such as "Turn around!" and "Move forward two units!" and plays games like tag, using an infrared sensor to search for people in a room. He can use this sensor to sound an alarm when a secured area is invaded by unwanted guests such as little brothers or small rodents. He makes happy and sad sounds and even gets in bad moods. (A simple command of, "R2, behave yourself!" snaps him out of it.) He weighs 6 pounds and is 15" by 7 1/2" by 10 1/2".
