In soccer stadiums I am famed, Making noise is my game. A funny word, four syllables in all, Can you figure out what I am called?

First, you throw away the outside and cook the inside then you eat the outside and throw away the inside

A body of water that proves that isolation is safety.

My heavy feet lay in hills or meadow, My spiky arms circle high or low, Upon them sharp black hairs do grow, While deep in my belly a fire does glow, Where delicate treasures do I stow.

I am produced by buzzing creatures, needed by cupric features, done by verbose teachers, and mimicked by Selene's reaches.
