Ankorodō Hiden Ninjutsu: Mochi Release: Infinite Dumplings

The user causes the dumplings near them to grow to enormous sizes. The constant growth makes it difficult for attacks to subdue the growing substance. Consumed dumplings will no longer grow.

Trivia

 * This technique apparently requires a second method to stop the growth, but the Ankorodō's owner forgot what it was, having not used the jutsu in years.
