Bowler or 10 gallon, fedora or such... if you can't find one you like there is no rush

There's a group of four, they are all guarding your coins. It keeps the fabric together that covers both the groins. John Cena holds you down and to seal the final score, he locks a sharp position and fixes you to the floor. Pierce social notes of interest to capture what you love. In a room with silent guests, you hear it falling from above.

I have a heart that never beats, I'm cold but I'm in every kitchen's elite. I keep things fresh but I'm not alive, open me and your snacks survive. What am I?

Pitted and stuffed is how I like mine, it also garnishes a martini just fine.

Head dangled down to rest for my feast. In lore, I’m seen as a shift for a beast. I whisper a sound you cannot hear, with skin that gives flight and might cause some fear. Hunting my prey from the lunar glow, mapping my way with an echo. What am I?
