Use your water breathing potion, and dive into the water.

Emboldened by your pouch of trinkets, you decide to go ahead and bust out the water breathing potion so that you can better explore the shallow waters of the islands sandy bay. You rummage through your bag until you find the bottle with that familiar blue glow shining through your clutter of trinkets. You remove the cork from the bottle using your pirate hook, and chug the fluid entirely, and after taking one final breath, you take a dive into the ocean, eager to find some aquatic pussy.

As you descend into the ocean you find yourself in a colorful coral forest with all sorts of marine life, though you have yet to spot any aquatic beast women. You do however notice a rather large octopus shambling about, and remain wary of its presence.
