Every time I distribute character points to my wolves, a leaf appears at the top of my screen saying, "You have found a leaf. Worth: 5 points". I don't really understand what it means and how to use these points

These leaves are from the current event, if ya go to news and go back with the arrows, you will eventually see the event news on it , where you will get more info on it c:

The leaves are like card collectibles that you can play with under Realm > Games > Leaves
