What could be better than relaxing by a small waterfall with your family? You were all relaxing peacefully. Birds were singing, the water was murmuring nearby, which seemed cold and deep, and the sun was already setting.Mom slowly collected all the things you took for the picnic, but at some point near the water you heard strange sounds similar to wheezing.Someone's head was peeking out of the water, but... it doesn't look like a human's... What now?
