Free verse is a poetic form that does not use formal rhyme and meter. That is why it is free - it doesn't have to stick to these formalities.
When Jack decided to sit with with Auggie at lunch his friends did not like that because Auggie was considered the "Freak" of the school.
I think its an Idiom. I don't see like or as. So no simile. I don't see he is something like a marshmallow. - No metaphor. I also don't see a non-human thing doing human things- the grass was dancing in the wind. My answer would be an idiom.
Hope this helps!
