The lost idle animation

Okay, the last post ended up way longer than I was anticipating, so I'll keep this one short. Sonic has one more unused animation, but the script itself is gone, so we can only guess the intended order and duration of each frame.

So what's the animation? It's an alternate ending to the idle animation in which Sonic falls asleep while tapping his foot.

Curiously, the sprites for this alternate sequence start at mapping frame $BF, directly following the regular standing and foot-tapping sprites at $BA-$BE. Meanwhile, the sequence shown in-game, in which Sonic urges the player to continue moving, uses mapping frames $AD-$AF, with the last sprite all on its own at frame $D9.

This suggests the sleeping sprites were added first, and the final sprites were later squeezed into any available slots. It would explain why no animation scripts use the sleeping sprites: they were likely part of the idle animation at one point, and then got thrown out when that animation was retooled.
