In one of the most bizarre incidents to ever occur in Ponyville, Pinkie Pie's Hearth-Warming-in-July party results in the reviving of a relic from Equestria's prehistory: A Neighanderthal. Cast out of his own time and thrust into a culture that is alien to him, he struggles to adapt. Luckily, the Mane Six have decided to help him find his place in the world. But nopony said it was going to be easy, especially since there is a twenty-five-thousand year span of history he has missed out on.
