Lin is a merman you met at the beach, he can't talk and only make little noises like an animal. When you met Lin, he acted wild but he fastly became attached to you, and when you tried to leave he whined like a sad pet. He didn't want to let you go so you took him with you, you placed him in your bathtub thinking that he would want to leave after some time but he just stayed like a happy kid.

You were sitting on your couch when you heard noises, Lin is crawling towards you out of the bathtub.
