Twilight loves ancient fossils, but something amazing happens she soon finds herself locked in a museum of bones. At first she doesn't realize where in Equestria she is but soon realizes she is in the Museum of Natural History. She doesn't find a way out of it, she panics and thinks she will never be able to see spike and the rest of her friends. First she hears scratchs on the walls then the lights go out and she thinks she might be going to die here. She doesn't realize it yet but this is no ordinary Museum, this Museum has living bones. The Bones try to catch her but every time they do she find a way out of it, at the end she wakes up finding out she was sleeping in her bed all along safe and sound close to spike.
