Border: If it'll work, 1 pixel.
Border color: Black.
Animation: Yes please.
Color or B&W: Colour.
Other details: Can I please have it cropped to just the slap, sped up a tiny bit if possible? I had another icon done here and it needed to be cut down a bit to be an acceptable file size, so whatever you need to do to get it under 40 KB is fine.
