This should be serially. You should write the name of your Biju, the number of tails, the animal, and its powers in this sequence.
Name: ***** (any cool name that sounds monster like).
Tails: eleven-tail gorrilla.
Power: controls wood and water. Mega tail beast ball and claws that cam rip any thing at all.
The next should be twelve-tail then thirteeneth and so on.
