For anyone playing Pokopia on NS2 and tired of guessing what each Pokémon needs to show up — I put together a searchable database with all the habitat requirements.
You can look up any Pokémon and see exactly what biome, items, and environment level you need. Covers all 200+ habitats from early game (Pallet Meadow) through endgame (Rocky Ridges).
Also has multilingual support if English isn't your first language (ZH/JA/KO/DE/FR/ES available).
Hope it helps someone — happy to fix any errors if you spot them!
