My niece is a mermaid puppy. None of us knows what that means.

She is very cute though, when I visit she gets shy the first day, by the second day she grabs my by the hand, sits my on the couch, and positions my arm around herself to cuddle.

She knows what she wants, even when I bait and switch her to explain fluid dynamics to a toddler… She looked offended when I explained to my brother how I used marbles to show her how valves and vortexes work, but she did understand the concepts
