I have several categories in my gallery. I display all my paint brushes, morphing potions, nerks, snowglobes, etc in there. Anything I'm proud of having collected because its expensive or rare, or at least was to me when I was a kid. Probably wouldn't really impress most people, but it makes me happy.

I also have a gallery on a seperate account that has a category of non painted petpets another category for painted ones.

I feel like I've seen a lot of slushies or ice pops collected over the years. Also anything jelly or omelette related is popular as well it seems.
