Millennials will probably remember Nickelodeon's Rugrats as a fun, quirky show about the hijinks that a bunch of babies can get into while lacking proper supervision. However, one fan theory takes a much darker view, suggesting that the babies on the show are actually figments of Angelica's imagination. She is a spoiled and lonely child, who has few friends, neglectful parents, and no siblings of her own. To cope with this, she invents playmates based on the dead children of her parents' friends. Angelica uses these imaginary children to vent her frustrations, through her bossy ways.
Wait, what? Dead children? That's right. This theory claims that Chuckie died in a car crash that also claimed his mother's life, which is why Chaz is always such an emotional mess. Tommy passed away during infancy, and his father Stu is in denial: he's constantly locked away in the basement, inventing toys for the lost son who will never play with them. Twins Phil and Lil were actually a single stillborn baby, but since Angelica never knew the child's gender, she imagined twins, one of each sex. Of course, this theory ignores the entire Rugrats: All Grown Up series, but that's okay—we prefer to pretend that show didn't happen, too.
