i just got to thinking that since pohatu is hydrophobic, he wouldnt really need a kaukau nuva. then i though if he fellin he could just run out then i thought since the kakama nuva lets u run through a solid object, and u can still breath while u are in it, y wouldnt that work under water?

Maybe but you aren't going through a solid object. Water isn't solid. If it was it would hurt to have a shower.

Moving to Theories...

i know water isnt solid, but still...(lol that would hurt)
