In one of the leaked folklore stories, a typhlosion grooms a girl and had a cold with her.
While the writing appears to be something along the lines gamefreak might edit down and make it more tame for a game, the translation of it is almost perfect and the weirdest part is there was no mistranslation of the Pokémon used, something that normally happens when leaks like this come out. At worst, it’s a recreation of Japanese folklore but with Pokémon instead of normal creature/yokai that just never made it and never got edited. At best it’s completely fake.
