On the surface, the Minun (named Peri) was relaxing while placing his top part on the surfing board and the bottom part in the water. Seems to be very calming at the moment, before his feet getting grabbed and without any warning he got dragged into the water.
While underwater he tried to swim up, but he gets dragged way deep to the sea and his eyes were shut, fearing that some type of creature would bring him under. He's scared, but he has to face his fear as he slowly opening his eyes to know what it was. Could be a Tentacool, a Frillish, an Octilery or some type of sea monster?
When he opened his eyes he sees something that did not expected.
It was Plusle. And she has fins and a fish tail. Peri's eyes were wide opened in shock. He never saw a type of Pokemon that's a Mermaid. He knew about Primarina and Milotic, but never would expect a different specie of Merfolk that lives in the sea.
Hibi as she holds his paws, pleasantly smiles to see the similar specie as hers but with feet instead of a mermaid tail. And she looked at his puffy cheeks and thinks that he's like a Qwilfish.
