Take Shelter is a 2011 film that the pups haven't watched but they figure it probably involves an apocalyptic event and people taking shelter somewhere, like maybe in a castle?
That's right, the Castle still stands, although the Knights of the roundtable have long since left the woods.
Note - This is not the final of the 2022 Night Cache, it's just an ammo can in the woods left by a group of very nervous geopups who are scared of Nocturnal Unicorns and Killer Klowns
