On a hard to reach island near Mexico City, Mexico, a little girl's spirit is said to roam. The man who found her dead body on his floating guarden's shore 50+ years ago, Don Julian Santana, was haunted by her tortured spirit. He found a discarded doll in the water. In honor of the little girl, he decided to hang the doll on the tree.
However, one doll wasn't enough. Any doll that he caught floating down the river ended up in a tree. Some dolls have missing limbs or heads, some body parts are missing dolls, and some are a modge podge of different body parts. Some dolls have been bleached while others look fairly new. When Don Julian couldn't find dolls in the river, he would buy some on his rare trips to the city. Soon, every tree was filled with dolls.
