Click the green flag and watch. You might have to click the green flag multiple times before letting the MAP part run through, or watch the MAP part and then re-watch it to remove lag. For MAP host: if you find that the MAP part is too laggy/goes on too long when you put the MAP together, you can always take the second perspective (the OC running) out and re-adjust the timing to fix the lip-sync afterwards.
MAP part stats: -OC (Flintpaw) by me. -animation (except color palette) by me. Color palette by @MAP_ATTACK. -MAP by @MAP_ATTACK.
