Shiloh Pepin, a Kennebunkport, Maine, girl who was born with her legs fused together, died in October at the age of 10. TLC crews were there to capture her last courageous months, and the film airs Sunday night.
TLC aired the first 'Mermaid Girl' documentary two years ago. A second followed earlier this year and Shiloh sadly fell ill shortly afterwards. She was the oldest of only three living children in the world with the rare condition known as "mermaid syndrome" when she died.
In the preview clip below you can see she stayed active and upbeat until the end. 'Mermaid Girl: The Last Six Months' airs Sunday at 8 pm on TLC.
