How be a creature that has been said to cry large amounts of muddy water full of bacteria. Most the creatures that live in the regions with this creature benefit from this for the muddy water is good for them and the bacteria is needed for them. They are not born with the bacteria, they have to be introduced to a water source that contains it first. When water is frozen over they may try to break the ice to dive in, if that doesn’t work they will look for another way to get in or just make their own water source that is about the size of a pond.
In fairytales they have been said to fall in love with kelpies. The kelpies love them back. The story’s some to vary on what they do with that love and how it happens.
