Will-Bot: Friend or Foe 11 years old

WILL-BOT is a small robot, who is afraid of everything. WILL-BOT lives alone on a small planet, which he patrols every day, hoping that nothing unusual will happen. One day a dark spaceship lands on the planet and a dangerous looking giant robot forces WILL-BOT to meet him at a chosen location. All hope seems lost, but is the strange visitor really a friend or a foe?
