You need to have a Lego WeDo to make this work. A whole new way to experience Lego WeDo & Scratch! Wait until the cat stops talking, then play around with the functions! Press the 'g' key to play a game. This was made for people who have a Lego WeDo. Plus, click the cat to turn the motor on/off. Also, tilt your WeDo to rotate the cat! Lastly, drag the slider to set the motor power. Have fun!! NOTE: When you win the game, you can not play it again because of an error in programming. Please press Green Flag to play again. Scratch on!
