A pie's flight ends in a splat (0x8005282c). The pie's template, 564 (model 885), has +0x0b = 1 in both levels 3 and 16, so both toss levels splat. examples/template_bytes.rs prints a template's record.

Each of the five bits is a flight (0x8008864c) with:

• flags 0x30705: kind 5, gravity 13, world collision;
• lifetime 2000 dt and bounce 1000;
• sprite 359 (TEXPOS + 0x10d4), half-size 200 x 200, face flags 0xd0800000;
• speed min(rand mod 150, 50);
• a direction tilted rand mod 2048 and spun rand mod 4096 (0x80088bac(pie, (4096, 0, 4096), 0, 2048)).

The two random numbers come from their own LCGs (0x800c41a4 and 0x800c445c, x 214013 + 0x269ec3), seeded as the executable has them. Kind 5 flights are drawn by 0x80088388 through 0x8008afc4: camera-facing quads like the box toss's arrow.

pie_toss::Splats spawns five where a pie stops: a wall, a hit or its range. It steps them (gravity, a bounce on the floor, the lifetime) and draws them with the pies. Seen in the port: the bits fly off the stall the pie hit.
