Frog and Lady bug
Create a world with a frog (Animals) and a ladybug (Animals). Write an interactive program to allow the user to drag the ladybug around the scene. (Use a let the mouse move objects event.) As the ladybug is dragged around, make the frog chase after it by moving one hop at a time without colliding with the ladybug. If the user moves the ladybug within 2 meters of the frog, have the frog look at the camera and say "ribbit"-then end the animation.
