A8F5: Handler: Wulf Pouncing
Handles the first frame of the Wulf pouncing (sprite IDs 58 and 5C). The timer in IX+02 counts down while the player is not attacking in the direction the Wulf is facing, and when it runs out the Wulf moves on to the second frame, which is handled by HandlerWulfLanding. The Wulf can hurt the player in the same way as in HandlerWulf.
