If your favorite artist had a tiny version that lived on your screen, would you get one?

I've been building PebbletsIO: Tiny animated companions that live on your screen, including little PopStars you can collect.
It's basically fan merch that's actually alive, hanging out with you instead of sitting on a shelf.

Got me thinking about all the merch I've held onto over the years.
The stuff you'd grab first in a fire.

So what's yours? The one piece of fan merch you'd never let go of, and why?
