More the exception rather than the general rule of what happens. The expression on Marisa's face here is suggesting a bad end and that nothing 'good' is going to happen to the yukkuris (unlike in that image, where the mother has a peaceful and joyful face). Of course, 6196 is just a single image, when there is much more of Marisas being unable to control themselves on water (let alone do a flip right after being born) and meeting their demise.
