Spider Transformation

is the unique of the Kumogani Clan of Yamagakure.

Overview
Much like, members of the Kumogani clan naturally have the ability to absorb natural energy into their body. By learning to control this natural energy, via their connection to the their clan is well known for, they can achieve a unique type of Sage Transformation dubbed "Spider Transformation" by members of the clan.

The transformation gives them a weak type of senjutsu chakra and physically transforms their bodies into a similar appearance to that of a spider, complete with additional arms and a third eye.
