What is my super power? And is 'you are so annoying' really a super power or not?

First off, of course it is. That has INCREDIBLE tactical value, and it worked just fine for Impulse too!

...surviving snow?

Second, your superpower is the ability to turn cheese into death.

Obscure, but situationally devastating.

Cheese into death... that sounds like an ingredient on one of those cooking competitions!

I had a friend in a D&D campaign who had a wheel of cheese as a weapon...

And yes, I can survive snow that goes up to my hips and stays forever!!!!!
