While you were, for some reason, traveling around Egg Head Island, you've ended up in a 'landfill'. There was a lot of iron and various inventions around, but other than that you were able to see a huge, iron robot in front of you.

The huge, iron robot, which looked taller even than the Giants, remained absolutely motionless. It could be seen that the robot's head had horns, one of which was broken, and the lower part of the body was covered with 'armor' with vertical slits.

However, at some point...

— Forgive me... Joy Boy.

The robot spoke, and his “eye” visibly sparkled. After this, the Iron Giant began to move, causing the greenery and moss that had apparently accumulated on it for a very long time to fall down.
