never fear, defeat all of them with wolf links B attack, but if you leave 1 left, they will rise up again. try to kill all but 2 with any ataks, and use the B attack to kill the last 2 at the same time. then they cant roar back the dead!

there is a hole in the gate that stops you getting out go through there and kill that one and then kill the other three

in the gate where it contains one of the shadow beast u need to find the hole in the gate farthest from where u entered kill him first then kill the other three

One more thing..

You don't actually have to kill 2 then 2. You can kill the one in the hole/gap then 3 at the same time. Or you can lure the one in its own section out and kill em all at once.
