From the front of the box: Look out! Here come the robots - a troupe twenty strong! - on the way back to their spaceship after making many friends on earth. But now it's time for them to go home. Can you help them board their spaceship? It's very unsteady when it's parked on earth, and when they step onto it, they really rock the boat. It's so tippy that when one steps on, two others may fall off. Find 1 - 4 friends and take turns balancing the rocky robots on their spaceship. Make a game of it - last one to add a robot without tipping any robots off wins the game! The robots are lots of fun to play with here on earth, too. You can stack them into interesting towers, and imagine all sorts of adventures for them. Set includes: 20 wooden Robots, 4 each of 5 colors 1 robot Spaceship 1 large, colorful Die Ages 3 and up
