Okay, so the method to get him out of the sand is as follows:

1. Lay barrel bombs

2. Use a sonic bomb near the barrel bombs to make him do his "eating lunge" attack, so he eats the barrel bomb.

3. Bomb explodes, he gets stunned. Approach him and press the button to fish him out. You must rotate the pad counter-clockwise to make it work.

4. Hapu is out. Attack his weakpoint for massive damage.

If you don't use the fishing rod (seems like you need no fishing lure), he will retaliate with a quick spin.

This is no longer about spamming sonic bombs, people. MH has evolved.
