I follow you without a sound I vanish when the dark comes around What am I

I have jaws but cannot bite, I grip and twist with all my might, What am I?

What redundancy? My name? Sure, they’re technically the same. First: Green, purple, red or white. Last: Cornucopias looming fame Together I’m still my last name though, and my first is also. If you dried me out like my first, the raise in would be colossal.

Find a four leafed version of me for good luck

I’m a tiny room that’s not for sleep, I guard your shirts and secrets deep. You visit me but never stay, I eat your mess at least, that’s what you say. What am I?
