As I said, we just wanted to have a bonus episode to show furry-furry scenes in our style. The horse guy scene will be either removed or added to the "fantasies" bonus episode - in which we'll show different scenes impossible otherwise, of which Naira is fantasizing with dildo during long evenings while John is in the village.
Talking of Halloween let's say it will become canon once we remaster it (replace the horse guy with John and finish the intended ending).
