Elephant and the Whale.
They are from the same series of animal designs as below's Woofie.
The design rationale for these character designs are pretty clear up till this stage.
This serie of animals are, mostly endangered, oh well.....almost all animals are joining the endangered category...sooner or later....
They are designed without limbs. This is to depict their vulnerability over the many situations, that our "superior" specie, or at least some of us who think they have the rights to inflict sufferings on other species, in return for more wealth, in spite of the necessity of life, food.
