"Daddy doesn't like me," or "Bobby thinks I'm ugly." Daddy never told his son he doesn't like him, nor did Bobby ever tell Suzie she's ugly - these are ASSUMPTIONS based upon an incomplete story coupled with an overactive imagination, and they can play terrible tricks on a young mind.
In the case of RobotFish, it awakens to find an awful "truth" - it's a robot... but it's ALSO a fish, and "robots and water DON'T get along." Why does it think it's a fish? Because it LOOKS like one.
