Lands

While Pokémon Smile has a specific backdrop of you brushing your teeth for when you are battling the Pokémon, when it comes to capture and when it comes to checking the Pokédex, each Pokémon is found in a specific land. This is the backdrop for when you catch it.

If you go into the Pokédex, you'll also see the land and be able to tap the Pokémon in the land. This will let you see their Pokédex entry.
