Ruby red or green or yellow, Sour, sweet, or even mellow. Slice me, dice me, eat me whole; In stories can be magical

I can be heard in caves or long hallways, but I cannot be heard in a closet, as you will not hear the phrase. You listen to me for twice or thrice but the time i'm there never lasts longer than a day.

I can burn, but I cannot fly. People use me to reignite flames from last night .

I yam what I yam I bring solemn and peas tomatoes potatoes some flowers and weeds. what am i?

A turtle, dove or kingdom I can be. No matter how cute I appear do not underestimate me. For I can devastate thousands in the blink of an eye or cause you to hole up and wonder and cry.
