You get up early before anyone else and you decide to spend the day exploring the ocean, via scuba gear. You didn't bring any spare wet-suit's with you, so you had to swim underwater in your normal swimsuit. You put on your oxygen tank, that come with a mouthpiece, and you even brought diving flippers to put on your feet.
You take the goggles, and rush towards the ocean, and dive in. You saw all the sea creatures under the ocean starting with flounders, lobsters, jellyfish, and even see turtles. You notice something glowing bright blue light near the sea sponges. You swim in through the sponges to get a closer look of what that light was coming from, and then you see that the blue light was actually coming from a sea creature glowing that exact same color you just noticed.
