すす, ゆす, そそぐ
You need to throw your two wolverines and your turkey into the oncoming tsunami if you want to wash them at the same time. It's the only way you can get them clean at once without the wolverines fighting over the turkey and somebody getting hurt. The tsunami is big enough to wash them all before anything bad happens.
Once they're nice and washed you need to subdue them by poking each of them with a tack (たく). The tack has special sleeping medicine on it, so once they're nice and clean you can put them back in their cages without them trying to eat each other.
