As I woke up, I noticed that there were some boulders encased in ice just a few inches in front of me. I slowly inched out of the blanket, and picking up ruby, I turned to Nat, and Jack, and began to say, "So, where to you want to train our dragons specifically??", but then, I noticed a waterfall, and noticeing Ruby still asleep, I thought of a good way to wake him up. I walked to the waterfall, holding him, then I dipped his head into the liqued. He flew up suddenly, and said, "What the-What the heck is this!!", looking at the waterfall. Getting and idea, I said, "Just go in it and move around without useing your wings.", and then, smileing, he said, "Whatever, sir!!", and dove into the water. I watched as he swam for a few hours, then I began to get sleepy again, when suddenly, he said, "Hey, I found a big dark circle shaped thingy behind the waterfall!!", and getting up, I said, "What...", and moveing around the lake the waterfall was in, I stuck my hand behind the waterfall, and to my suprise, I found he was right. Turning to him, I said, "You can stop swimming now. You can come with me.", and ruby grinned, and getting out of the lake, he shook his wet wings, and flapping them, he soared into the air again, and hovered right beside me. I jumped into the tunnel the waterfall had, but I still got wet. I turned to Ruby, who was so frustrated with not being able to get through the waterfall flying, he unleashed a huge flamethrower that he kept up before he got through. As we explored deeper into the cave, 5 small, white worms in different areas, were watching all of our dragons..
