Boss: Naval Piranha
A giant Wild Piranha attacks by charging at you. To defeat it, hit the boss's belly button with an egg three times. You can't hit it from the front, so bounce the egg off the opposite wall and use water skipping to hit it. When you run out of eggs, eat the Nipper Plants that the boss spits out to replenish them.
By the way, standing at the very left edge of the platform in the room, Kamek won't appear, and the Wild Piranha won't grow larger. From there, you can defeat the Wild Piranha with just one egg.
