Doton with Jacob.

[Mockingbird]

I listen to your instructions as I still hold the play dough type rock in my palm. I'd then insert a small amount of chakra into thus giving me the ability to mold it. Since the rock is no longer hardened I easily shape the rock into a normal sized, brown kunai. After shaping the dough into a kunai I manipulate it once again but this time I manipulate the texture again instead of the shape to make it hardened with a sharp tip. I'd then spin the earth made kunai around my right index finger before throwing it at a passing bird.

Oi, why in hell would you throw the kunai at a bird if Earth is life? o_o The bird did nothing U_U

And you weren't supposed to throw it. You were going to make it into a shield afterwards.

*Hands you a new rock*

Now turn that into a shield that protects a majority of your upper body o_o
