Miko has a point. More than one. A metal surface that's not textured would be easy to slip off of. Even if it's a pain, snow might still be the safest. Even if it does break apart, well, there's only snow involved and snow doesn't hurt.

A lot of work, but when making the Biggest Ever of anything, one kind of has to expect that.

"Have you built a lot of... giant snowmen before?" She's guessing never this big, but. Miko's practiced this before, right?
