Cuanakrys wandered into the water unknowingly, jumping out when she discovered it was a little cold. Note 'a little'. Even if it was only a little cold, Cuanakrys still hated the cold, and looked up to see a huge, towering waterfall, yelping "What the furnace is THAT?" and tried to swim up the waterfall. She failed, doggy paddling back to shore, with water in her mouth.
