Underwater entrance!

So, now you have found the Magicain of the Seas hiding place. The problem is that it's a very good hiding place... How to you get on that Island? Claimb? But just as you're thinking about that, the pirates dive down again. All you can do is follow. As you swim closer to the Island under the surface, you can see a huge opening in the mountain. It's a cave! It must lead inside! You're lucky to have won the trust of those pirates...

Enter!
Dive to the bottom! (OBS: Red Newbie rank is needed!)
