Bulbasaur/Ditto - The Bulbasaur in the cave are really Ditto. However, if you take a picture of them as Bulbasaur, they're judged as Bulbasaur, so lure them together with some Pokémon Food. To turn them into Ditto, hit them with a Pester Ball. Use Pokémon Food to get all three together.

Grimer - Take a picture of the first Grimer you see to make another one appear on the ledge next to the Ditto. Take some nice close up pictures.
