Handler for the object types 52 to 55 the gargoyle (see Sprite_Gargoyle_1). It is a flying creature that is handled like the jellyfish (see Handle_Jellyfish), and it shares the routines that animate and move it.
When the gargoyle is in a different room x from Sabreman, its y velocity is set to a random 32 or 224 (see Choose_Random_Velocity) and Move_Creature_Horizontally moves it towards his room. When it is in the same room x but a different room y, its x velocity is set to a random 32 or 224 and Move_Creature_Vertically moves it towards his room. When it is in the same room as Sabreman it is animated and moves in the same way as the jellyfish (see Handle_Jellyfish_Set_X_Velocity).
