Pikachu - Take a picture of the first Pikachu you see, then take another, and then a third one. After the third picture, Pikachu will jump on top of the rolling Electrode, which makes a really nice photo!

Electrode - Take a picture an Electrode as it explodes. If you miss the first opportunity, hit one with some Pokémon Food or a Pester Ball to make it explode.

Electabuzz - Hit the first one you see with some Pokémon Food or a Pester Ball to make it fall down (not in your path however) and then after you pass it, take some nice shot's of it getting up. Or take one near the T.Vs are throw an apple and take a nice shot when it's eating.

Kakuna - Everytime a Elctrode explodes, they decend to the floor. Take a close up shot to get the best score. Lots in the pictures are good, but it won't get you the highest score.

Zubat - As soon as the doors to the cave open, a Zubat will fly out at you. Snap some pictures fast. Turning around for a picture doesn't work.

Dugtrio - After you snap Diglett in the third spot where it comes up, a Dugtrio will surface. Take a picture of the Dugtrio to get it to come close to you

Magnemite - Throw some Pokémon Food out to get a nice picture of one.

Magneton - If you throw out enough Pokémon Food, the three Magnemite will come together. Snap some pictures before you end up going back to the lab.
