Quirky, quick, and enjoyable enough for a +1, but I feel that I would have liked it more had it ended here:
SCP-4647-1 instances are driverless and fully capable of self-locomotion, and will attempt to drive into the surrounding wilderness upon exiting the mirror.
Because unlike SCP-3900 that Kirby mentions upthread, the final event feels a little too far out there. The wolves, as wild as they are, still have an a semi-clear underlying logic to when things go off the rails, and that seems to be absent here. It seems crazy simply for the sake of it. Alternatively, perhaps a touch of sinew to suggest what was different this time around would help it flow a little neater.
