Patrick approached nervously until they noticed him. The three merpeople gave him warm and friendly slimes as the beckoned him to them. Patrick's childish side jumped into the pool and swam over to them rather sloppily.
They met him half way. "Your a rather adventurous boy, not to mention an adorable one too." The mother said, booking his nose, making Patrick grin. "I'm Marina, this is my husband Aquarius and our daughter Pearl. We're your host family. " Marina said.
"Host family?" Patrick said, speaking for the fist time since his change. " that's right, as a merchild, your too young to look after yourself, so for the duration of your visit, we'll be taking care of you." Aquarius said.
"Can I call you mama and papa?" The little boy asked. Their faces lit up. "Of course sweetheart." Marina said happily.
"Well little brother, let's get you a tail." Pearl said, fawning over how adorable her new baby brother.
They lowered him waist deep. Before long, Patrick's trunks and legs vanished, replaced with a sea green tail. He moved it around in ways impossible for any ol' costume.
