What is a plausible impossible? Well, for example when a cartoon gets hit with a giant hammer he becomes totally flat, its plausible because it makes sense that being squashed would leave you flat, but we know that its impossible. The video Night On Bald Mountain has many plausible impossibles.
The first plausible impossible i noticed was the beasts shadow. The beast is controlling his shadow down the cliffside. This is plausible because we can control shadows by moving, impossible because he moves the shadow without moving to cast darkness on the small town.
Next, ghost riding ghostly horses. Plausible because horses are rideable so why not have ghosts riding ghost horses. Being ghosts and all makes it impossible, ghosts ether real or not don't ride horses and terrorize small villages . Under the circumstances of them being called from the grave by the beast-devil thing makes riding forth from the grave believeable.
In this picture demons are jumping off a cliff and turning into shades or flying beasts from below. It is plausible because their demons which are supernatural so morphing isn't unbelievable. Its impossible because things cant morph quickly into something. It makes since because the evil in the video is suppose to be scary so demons morphing makes since.
Finally the demon being defeated, curls up his wings around him and turns into the tip of the mountain. This is possible because being the right shape and being magical,turning into a mountain top makes sense. Its impossible because becoming a mountain top is obviously impossible, going from flesh to stone isn't possible, but it is believable.
