Some people like me, some may not. I can be cold, or I can be hot. Maybe I can smell of Lavender. I am not animate, so I may not wander. I can ease your pain. And still you can gain. What am I?

I’m brown and hairy, but not an animal. I’m filled with water, but I never drink.

Light or heavy go to town, Turn to smiles each every frown, Laughter, giggles, thrill, and glee, As one goes up and one goes down

I guard the sea's treasure, a fortress so small, Echoes lull within my spiral hall.

I'm green at the start. Halfway through I'm mostly red with dark freckles. By the end, I'm often smiles of green, white, then red.
