In the movie for "Miss Peregrine's Home for Peculiar Children", for the scene where Miss Peregrine shoots the hollowgast at the cliff side, there is already an outline of where the hollowgast's body will fall. If this is inside the time loop, where did the outline come from? Would it not just disappear the next reset since the hollowgast had not yet died? In other words, how did they know its exact resting position and who put it there, before the actual event happened?
The time loop is not absolutely fixed. You could make the same argument for the catching of the falling squirrel.
It is mentioned elsewhere in the film that villagers visit the home and Miss Peregrine only kills them if she has to. Also, Abe can call into the loop to report on his searches in the outside world. So, events can change in the loop from 'day' to 'day' as the loop re-runs.
We must assume that the outline was drawn after the first time the hollow appeared.
