I am always hungry I must always be fed The hand I touch Will soon be red

My brother likes the salt, I do not, my brother likes the letter v, I’m more inclined to u, my brother is bigger usually but I can get big too!

I have a bed, yet I never sleep. I run without rest, always moving forward. In the end, I meet my brothers, and together we become one.

I ooze confidence and ride high on clouds of rainbow. I have the strength of lions but come at a cost, for I tempt to fall those who are lost.

I am born from the moon, but I do not come from outer space. You feel me when I push and pull.
