Hey, I was just wondering of anyone knew what/if the bells around town do anything?

I have found 3 in Grid and Uldah ( have not checked LL yet.). You can target them and ring them by hitting it with a /snowball.

I did the first part and got my deer suit already but now I'm wondering about these bells.

I also just found a random ??? outside the tanners guild in grid but when clicked on it say I find nothing.

Anyone have any ideas?
