If the sheep are jumping over the fence near the speed of light, and the observer moving with less velocity, the local time for the sheep will be slower relative to the local time of the observer. Following this, if the sheep and the observer are at rest but the sheep are situated closer to a large gravitational mass time for the sheep will be passing slower relative to time for the observer.
So if the sheep were jumping over a fence with infinite mass at the speed of light, they might never make it to the other side from the viewpoint of an observer at rest.
