Handles a hippo (sprite IDs A4-A7) or a warthog (sprite IDs AC-AF) which is asleep. If BringActorCloser has moved the animal to another room then it wakes up as a hippo or a warthog chosen at random (see WakeAnimal).
If the player touches the animal (see TestActorHurtingPlayer), unless the start-of-turn delay is running or the player is not alive, then the animal wakes up, turns around, stands still for a short while (the counter in *IX+02) and makes a noise.
