You play Puffle Rescue on the black puffle level and at the beginning when you save the first puffle, a giant squid will come over you. Follow the squid and bubbles will come out of him and the bubbles give you air. He will lead you to a hidden staircase that is the underwater room. The key is located in it called the "Moss Key".
