My prediction came true!

Think about this. Akantor represents Fire because it is a hellish-looking beast that tends to be found in volcanic areas. Ukanlos represents Water because it is turtle-like in appearance, lives in polar areas, and can utilize ice in battle. Odibatorasu represents Earth because it is found in deserts, is much like a tortoise, and manipulates the sand when it attacks.

Now let's look at Poborubarumu. This whale is just as big as Akantor/Ukanlos/Odibatorasu. It lives in the Highland, which is dominated by cliffs that reach the sky. It produces wind in the form of sound waves.

Therefore, Poborubarumu represents the fourth and final element - it represents Air!
