Covers sprites $94 to $9B, two creatures of four codes each: $94-$97 a cloaked figure, $98-$9B the third kind of bat. Every 32 passes a random velocity, x from bit 2 of FRAMES and y halved; the picture faces left or right by the sign of +$08 and flaps between two frames. MOVE_WITCH is the same with a period of 16.
