I am a cozy cocoon, a portable bed, I keep you warm when the stars overhead. Unzip me for rest, then roll me up tight.

You serve me, but the person you serve me to doesn’t eat me. What am I?

I’m a note to a friend and a national monument, but I fit within an envelope. What am I?

A fall from the heavens in the shade of a tree A lifetime of sun is waiting for me I have a hard shell but break through and you'll see I hold the future of the forest in me

What do you drop when you need it, and pick up when you don’t?
