Mew
Use the following technique to get an easier photograph of Mew. Once in the Rainbow level, pop Mew's energy shield by throwing Pester Balls at it. Then, use the Dash Engine to keep up with Mew for a minute, then snap away when he turns around to look at you. This must be done quickly before he returns inside the energy shield.
Another technique is to hit Mew with a Pester Ball while it is chasing the energy shield. It will start spinning in place for a few seconds before disappearing. To keep it from disappearing, keep throwing Pester Balls at it. Do this through the whole level to keep Mew in front of you the entire time.
After the second time Mew flies at you in its energy shield, turn your camera to the left and up slightly. When Mew flies by it immediately does flips. Take a close-up of it in the classic curl position while its whole body is towards you, with the light behind it. This results in a photograph worth over 8000 points.
Moltres
Go to the Volcano level and follow the path until reaching an egg in the middle of the road. Then, throw an apple at the egg to make it fall into the lava and Moltres will appear. Note: Wait for it to face you for additional points.
Muk
Shoot Pester Ball at the Grimmer in the Cave level to evolve it into a Muk.
Pikachu
Play the Poké Flute in front of Pikachu in the Beach level to have it use a Thundershock attack for a better photograph.
Throw a Pester Ball at the Zubat that is carrying Pikachu in the Cave level. Pikachu will come down attached to balloons. Next, it will run over to where Articuno is found. Release Articuno with the Poké Flute. Then when approaching the end of the level, look behind to see Pikachu riding on Articuno.
Throw apples towards the Surf Board in the Beach level immediately after seeing Pikachu to have it pose on the board, including backflips.
After flushing Scyther out in the Beach level, two Pikachu will dash out and jump up on stumps. Play the Poké Flute and they will start zapping. The photo of Pikachu on a stump with a Thundershock is worth a lot of extra points.
Take a photograph of the first Pikachu that appears at the beginning of the Tunnel level. He will run backwards. Take another picture of the Pikachu and he will jump on Electrode. Take a photograph of that scene for extra points.
Get a photograph of Pikachu on a ball for 500 extra points. Get a photograph of surfing Pikachu for 900 extra points. Get a photograph of Pikachu on a stump for 2500 extra points.
Porygon
Go past Vileplume's location in River level. Pass the Metapods, then look right when you see Psyduck near a lot of logs. Hit the wood-appearing objects that are flying around with a Pester Ball and Porygon will appear. Hit it with another Pester Ball and it will change into its original colors.
Rapidash
After the first Rapidash runs by on the Volcano level, two more will appear on the right. Throw an apple at them and they will start reigning. You can get more points for your photograph while they are on their hind legs, because of their size, and since there are two of them.
Sandshrew
Hit a Geodude down with a Pester Ball in the Valley level and Sandshrew will appear from the ground.
Sandslash
Look towards the first Mankey near the beginning of the Valley level. Something that resembles a Kadabra will appear further down the level. It is actually a Sandslash. Take a photograph of it when it goes into the ground for more points.
Get to the area in the Valley level where Sandslash, Graveller and two Geodudes can be found. After they hide, throw Pester Balls at the two Geodudes. After they fall, Graveller will follow. When it hits the ground, Sandslash will pop out. You can get a nice close-up of it as it appears for more points.
Shellder
A group of four Shellders can be photographed near the Slowpoke area in the River level.
Slowbro
Throw apples at the Slowpokes that appear near the wooden Shellder sign in the River level. Then, lead them to the mud spot next to the sign. The Slowpokes will put their tail into the water evolve into Slowbros after hitting the Shellders.
Slowpoke
Throw apples near the wooden Shellder sign in the River level to attract a group of Slowpokes.
Snorlax
Play the Poké Flute in front of Snorlax in the Beach level to wake it up for a better photograph.
Squirtle
The little bumps in the water at the start of the Valley level are Squirtle shells. Throw Pester Balls at them and they will shoot onto land. Then you can take close-up photographs, without them fleeing like the other Squirtles.
Starmie
Take a photograph of Staryu in the center of the Valley level. Then its gem will turn blue and it will begin to circle you until the whirlpool appears. Staryu will enter the whirlpool and come out as Starmie.

Go to where a lot of green smoke is coming out of a flower top in the River level. Play the Poké Flute and Vileplume will come out and dance. Press C-Down again to see a different dance. This may be done again until all four dances are seen.
Zapdos
Go to the Tunnel level. Then just after the first door you will see a Pikachu next to a large egg in the distance. Throw some apples to lure the Pikachu closer to the egg. When Pikachu gets close enough, play the Poké Flute. Pikachu will start a Thundershock attack and zap the egg. The egg will hatch and Zapdos will appear. Note: You will need Zapdos to shock the generator if you want the Pokémon sign.
Zubat
Every time a steel door opens in the Tunnel level, a Zubat will appear.
Finding the six Pokémon signs
After completing the Valley level by hitting the Mankey on the switch, Professor Oak will tell you to take photographs. Here are their locations:
- Kingler
On the Beach level, after passing Pikachu, turn around and take a photograph of the rock with seaweed that resembles a crab.
- Pinsir
In the Tunnel, wait until Zapdos has hatched and turns on the power. Then when you pass the Electabuzzes and Pikachu, look to your right to see Pinsir's shadow on the wall.
- Koffing
In the Volcano level, throw a Pester Ball into the small volcano to the left of the first Rapidash that appears. Then, smoke in the shape of Koffing will appear.
- Cubone
In the River level, play the Poké Flute in front of the sleeping Vileplume. Then the smoke will disappear and a tree in the shape of Cubone will appear.
- Mewtwo
In the Cave level, after hitting the two Koffings chasing Jigglypuff with apples, turn around to the left while near Weepinbell to see some bright crystals/stars. Then, take a photograph and it will turn out to be Mewtwo.
