I know you can find water Pokémon near water, and grass Pokémon near… well grass. But what about Ghost/Poison/Psychic (let’s just say “GPP” for short) type Pokémon?
I heard a rumor that you can find GPP Pokémon at night, but the only GPP Pokémon I’ve caught have just been in random suburb areas during the daytime, along with grass type Pokémon. Is there a specific location where you can find GPP type Pokémon? Or are they just rare and randomly placed?

It has a chart at the top showing what percentage of Kanto pokemon belong in each type. Below, it shows a list of all Pokemon in the game and after that there is a chart showing what type of Pokemon to expect in various Biomes.
