[ExpHP]

TH11 pl01.anm has these:

entry {
    path: "face/pl01/face_pl01no.png",
    img_width: 256,
    img_height: 128,
    memory_priority: 0,
    sprites: {sprite77: {x: 0.0, y: 0.0, w: 256.0, h: 128.0}},
}

entry {
    path: "face/pl01/face_pl01no.png",
    img_width: 256,
    img_height: 128,
    offset_y: 128,
    memory_priority: 0,
    sprites: {
        sprite91: {x: 0.0, y: 0.0, w: 256.0, h: 128.0},
        sprite92: {x: 0.0, y: 0.0, w: 256.0, h: 128.0},
    },
}

entry {
    path: "face/pl01/face_pl01no.png",
    img_width: 256,
    img_height: 64,
    offset_y: 256,
    memory_priority: 0,
    sprites: {
        sprite93: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
        sprite94: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
        sprite95: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
        sprite96: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
        sprite97: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
        sprite98: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
        sprite99: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
        sprite100: {x: 0.0, y: 0.0, w: 256.0, h: 64.0},
    },
}

Truth should be stitching together three images for this.
