To be exact, those are three frames ^_^ On the sprites itself, basically what Raven said... other than that, the throwsers look strangely shaded, as on the second frame they have a dark finish, while I can't see anything like that in the idle frame. Other than that, I think the pale colors could somehow vanish between the default RTP colors, so if you're using default sets, make sure to decrease the saturation a bit if you don't want to change the sprites colors.
