Looking for a specific anime

Hi, I'm new to Conan and came across an episode on YouTube Shorts that really peaked my interest. I did...not know how many Conan series there are and co and was wondering if someone might point me in the direction of it? I've tried googling and websearching but after about twenty minutes it's still just giving me some YouTube summaries of the episode by fans that don't actually highlight which series/episode.

The case was the mermaid who drowned in her shell during a show and Conan figured it out due to her lipstick in the dressing room, to keep it as spoiler free as possible.

Not sure what specific series this is from but I'd be interested in checking out the show it's from — or if whatever series it's from is a bad starting point, if there's a better one to start with, I'd be interested in hearing.
