Many of your beloved Disney movies were based on folk tales and original novels -- but they didn't have the fairytale endings.
If they hadn't changed the story, it would be pretty terrifying indeed.
According to Movie Piot, in the original, and horrifying Hans Christian Andersen tale, the mermaid has her tongue removed by the Sea Witch, instead of the Disney-friendly voice removal.
Not only that, but the mermaid is doomed to horrible pain every time she walks on human legs.
And after all her troubles to become human, her beloved prince actually chooses to marry someone else!
In the end the mermaid drowns herself in the ocean, and her body is transformed into sea foam.
Check out the gallery below to see the harrowing original endings as illustrated by College Humor.
