So I go daily to the Polar Ice Fields, because they are part of my dailies, but I have actually no idea where it leads to/is supposed to go. Is there an end? Is there something to reach (or not)? And why do I get Frozen Cookies I never actually get? :P Someone who knows what this daily walk into the icecold polar fields of Arctic Frost is about?
- There is an end to it. The prize is a Bucket of Polar Water, which can be used to create a Glacier Potion to turn your pet Glacier. I think there might also be another random prize or two you can get while working your way through the ice fields, but I can't remember for sure.
The frozen cookies are needed to make it past an obstacle further into the ice fields, so they don't exist outside of the game. It's entirely random whether you get the cookies (and make it past the obstacle) or not.

I've been dipping my frozen cookies in buckets of polar water for ages. Yum yum! That's why I never end up keeping the cookies ;)
But then, my cookies sometimes attract polar bears so I need to fend them off with my trusty polar bucket handle.
Don't take my word for it though. I think I confused the order of my story and which caused what, because walking in circles for months makes me dizzy!
A list of all the cool (no pun intended... maybe) stuff you can find in there can be found here. There are 12 total, including the bucket.
Also thought I would mention that you can do it more than once a day. Not sure of the frequency but it is fairly often.
Yeah, it seems to be every few hours or so. But you don't get an alert when you can go again like some other things, so you just have to remember to check on your own.
Actually there is an alert. If you refresh the page when you reach the end, it gives you the 'set an alert' option.
Oh, thanks for that! Still kind of weird that you have to refresh the page though, I think they should add the "set alert" button on the page where you actually reach the end.
