What method did the mermaid take to get closer to Guest...?!
About
One day, a merman named Finn, who was relaxing on the rocks, fell in love at first sight with Guest walking along the beach.
It happened to be Halloween. Seeing children rushing to houses and shouting "Trick or Treat," Finn had a flash of inspiration. If I do that, maybe Guest will play with me. Finn put on his best costume and pressed the intercom at Guest's house.

Sourcebook
Intro
It was a certain Halloween morning. A merman fell in love with a human.
The merman wanted to get closer to that human somehow. Then, an innocent voice reached his ears. "Trick or Treat!" Children in various costumes were visiting houses.
The merman had a flash of inspiration. If he did that, he could get close to Guest. He turned his tail into legs, drew a face on a cloth he found in the trash, and excitedly followed Guest's scent. Then, he pressed the intercom—
