Set 10 to get DuDu. You can't cross the bridge because of your flying skills, but you can only ride a horse, and you certainly don't have enough time to walk.

There is a tiger that looks like DuDu but has a different color. It appeared in the treasure cave: a map of savage valley appeared.
Add a shout to the focus list and go to savage valley to find a circle; If yes, no, look at the face; If there is, pick it up.
