With the new update out, new shops appeared for a hub quest. They grant you items to buy a suit for the ice cave. I was thinking they could be used for something else.
The shops can be used to buy winter cosmetics, such as a snow pile (treasure wars treasure), a snow ball (murder mystery throwable), and a snow flake (sky wars spawn vehicle). You could also be able to buy the eskimo (or coat) from the shops, which you can then wear as a costume.
This might be hard to implement with the time The Hive has, but it would be a really cool feature.
