Earlier today I did a thorough inspection of the swimming pool. While doing so, I did in fact come face-to-face with this aforementioned creature Edogawa-kun and his new friend keep endlessly raving about.
You win this time, Edogawa-kun.
However, it declared that it would appriciate it if you called it by its actual name, which happens to be Frankie. I may as well respect its wishes, for... Erm... I don't want to find out the hard way what this creature can do.
This was enough excitement for me for one day. I think I need a rest.
