This is a location you can hunt in, but it is just basic mice present here. There is really no reason to hunt here.
There is a general store and charm shop that has all sorts of goodies to buy, but you have to have King’s Credits to buy them. You get those from catching some mice, leveling up, and in daily rewards.
Other than that, there is little to recommend here.
Contrary to how it appears, you don’t have to sign up for tournaments in this location. The Tournament Hall is simply a place where you can spend your tokens from winning tournaments (like the tournament bases). There are also some hunting kits that you can purchase with tournament tokens as well.
As for the mice here, you can hunt for them, but honestly, there is no point.
