I am related to water, but I am not a liquid. People often imagine shapes with me.

I multiply without birth, feeding on form. My presence ensures every calm finds its storm. The more I gather, the less remains whole. I am time's true current, taking its toll.

I am an organ, but I am also a verb. Digital me sometimes cost money, but sometimes is free. I come in many colors, but I need to watch out for the sun.

Three is common, four is rare, more is an anomaly. Pluck me gently if you wish, for I may bestow you luck, but only if you look below.

Golden crescent fruit, Doth slip from its yellow skin, Sweet within, dost hide.
