Given that Stone Soldiers was inspired by the fantastic TV show "Supernatural" it seems only fitting to kick off a Supernatural 12 Days of Christmas by mentioning the "Supernatural" Christmas episode from Season 3: "A Very Supernatural Christmas".
In this early episode in the series,. Sam and Dean travel to Ypsilanti, Michigan to investigate another unusual murder. Along the way, they encounter two monsters posing as happy humans celebrating the holidays by sacrificing victims--to each other.
This episode also features flashbacks to young Sam and Dean as kids, and a very Holly, Jolly weapon they use to end the monsters' Holiday Hunting.
The best part about this episode is that you can own it. Season 3 is available on DVD at Amazon.com for only $34.96 ($18.13 for Prime customers)!
