The blue whale is a marine mammal and the largest of all the animals to have ever existed, larger than the largest dinosaurs.
In Scribblenauts Unlimited, it is a gentle whale which is slightly larger than a regular whale. They are neutral creatures, that only attack in self-defense. They have 80 health points and their bash attack deals 30 points of damage.
They are carnivorous, they will eat small fishes, shrimps and krill. They are protective towards members of the same species, becoming hostile if you attack one. They will run away from the whaler. They will randomly show from their blowhole.
