I frequently notice that there appear to be "somethings" coming out of simple "rocks"... but we all know that a rock may not always be a rock when it comes to nasa image tampering.... but anyways I have two images of the same individual lifeform from two different Sol dates. In one image the lotus/tulip shaped lifeform is just sitting there and in the next it appears to be defending itself from the Rover. Very slightly but still noticeable.
