A little help needed

[Guest Renegade]

I'm in Atlantica, at the point where you have to grab onto the dolphin so it takes you to the sunken ship. Problem is when I tag along to it, it just goes around in circles again and again.

 

Any help please?

Make sure you kill all the enemies in the area.

And the most confusing and annoying boss too.
