In the deep and large waters of the ocean, a blue whale hunted for plankton and small fish for food. On their own, blue whales can eat almost 4 tons of food in a single day, which is huge.
But nothing compared to the area's large sea monster, Oceana, which can eat 1000x the amount of food a blue whale can eat in a single day. Even the blue whale, which is however the biggest mammary and animal in the world, can become a small meal for Oceana, if a blue whale passes at the wrong time in front of the big kaiju if it is suddenly hungry.
Fortunately, the magic of Dreamuria avoids that there is too much loss of fish by making reappear, but only those which have been eaten in too much quantity, beyond a normal quantity consumed by an animal in the oceans. Because without that, it will be a long time since Oceana will have emptied the oceans because of her great hunger, without doing it on purpose.
