Change your animal
One of the cool things about WildCraft is that not only can you play as a wolf or a fox, but you can also play as animals such as a lion, bear, or even an eagle. This is where chests come in handy again. On occasion, you will earn some gems that can be used to unlock new animals.
It's always fun when you can a chance of style. You can even unlock crocodiles or horses (Kentucky Derby anyone?). Just keep in mind that some animals cost more gems than others. For example, the lion will cost 40 while a horse will cost 90 gems.
This is because certain animals are Rare while others are Legendary. So as you can expect, the Legendary ones are worth more than the Rare ones. Now, you might ask yourself "why is the horse more legendary than the lion?". I think that's simply because something like a horse may seem out of character being in a game about essentially being a predator so it's kind of funny and cool.
