Struct Crab 

pub struct Crab {
    pub id: u32,
    pub tile: u16,
    pub dir: Direction,
    pub progress: u16,
    pub prev_tile: u16,
    pub prev_progress: u16,
    pub prev_dir: Direction,
    pub handed: Handedness,
    pub kind: CrabKind,
}

One crab. Position is integer-only: the crab is progress subunits past the centre of tile, moving toward the centre of the next tile in dir. prev_* hold last tick’s position for render-side interpolation (spec §7.4) and are never read by the simulation itself.
