Sebastian

Hello, it's Sebastian, the friendliest crab in the sea! Lately living down here has been very difficult. I have noticed that there is a huge change in our oxygen levels, and its affecting all of my friends under the sea! King Triton has sent me out, as his royal sidekick, to ask for your help to figure out what's causing this disaster. Once you can tell us the source of this problem, we can find a way to fix it! This inbalanced level of oxygen is causing some of our sea creatures to die, and an overgrowth of others! The water appears to be turning black, and it smells very bad. It also seems as though the microbes which usually break down and purify organic wastes have been stopped. Please help us before it's too late!
