One of the youngest and most intelligent minds, Dexter hides a private laboratory within his bedroom that extends far below the house. From here, he has experimented with countless machines and inventions, yet his ambitions have either failed; or been destroyed by his sister Dee Dee, who is usually in the way of breaking into his lab. In spite of it all, he lives in an average suburban home with his mom and dad, both of whom are unaware of his secrets.
Dee Dee! Get out of my laboratory!
