Cynthia Doll

Origins
The "Rugrats Theory" is a creepypasta that speculates the origin on the 90s cartoon, "Rugrats". In it, all but a few of the infant characters are, in truth, schizophrenic products of Angelica's mind. In the later reboot spin-off of the show, "All Grown Up", the hallucinations continue, and Angelica dies at age 13 of a drug overdose.

Effects
The doll is capable of inducing schizophrenia in user, leading to hallucinations of children, infants, and drug addiction, which in most cases can and may very well lead to death by overdose.
