gather wind chakra in my body and channel it in my lungs. I take a deep breath and blow out, as I blow out I use nature transformation to change the nature of my chakra to make it more fast and free, turning it to winds. Afterwards I use shape manipulation to shape it into a single penguin. I then do the same and shape it into four different penguins.
Advantages: you can make up to four and it requires mo handseals!
Disadvantages: the four penguin are D rank each >_> but the bigger penguin is stronger :3
