Theory of Rugrats

The theory of Rugrats

The Rugrats really were a figment of Angelica's Demonic and Unimaginable imagination.

Chuckie died in 1986 along with his mother, that's why Chaz is a nervous wreck all the time.

Tommy was born in 1988, but he was a stillborn, that's why Stu is constantly in the basement making toys for the son who never had a chance to live.

The DeVilles had an abortion in 1990, Angelica couldn't figure whether it would be a boy or a girl thus creating the twins.

As for "All Grown Up" the teenage Angelica became addicted to various narcotics which further aggravated her Schizophrenia, bringing her back to her childhood and thus her creations she obsessed over, because of time lapse between the present and the last time she interacted with her creations, she made them older. Angelica was constantly taking hits of acid, so she would never have to live without her creations who were her only company. In a judgmental world, Angelica's mom actually died of a heroine overdose in 1982 just after Angelica was born, and Drew in his depression married a gold digging whore that Angelica idolized because she fooled herself into thinking it was her real mom but always had a concept of her mom, Cynthia, and took a barbie doll and made it after her mom's image, wearing an unwashed orange dress and having jacked up hair, which is why she was so attached to it. Later in life she followed in her mom's footsteps with drugs and everything, dying of overdose at age 13 when All Grown Up! was "cancelled".
