Kranua

Kranua were an extremely special type of Vahki built by Nuparu for law enforcement purposes. They were very large and powerful, and could turn their bodies into grains that could flow under small spaces to pursue Matoran troublemakers. Their staffs could turn anything into grains of protodermis.

Behind the Sets
A Kranua can be made by combining the Rorzakh, Nuurakh, and Vorzakh sets.
