Charizard
To photograph a Charizard, throw an apple at the Charmeleon by the lava pool near the end of the volcanic level. If you knock him in the lava he will evolve into a Charizard.
Find The Three Mythical Birds
Each of the three birds will be in an egg.
1. The first Mythical bird is Moltres (he is in the Volcano level), he will be easy to find since his egg is blocking your path. all you have to do is hit the egg with pokemon food or pester balls and a moltres will emerge from the hot lava
2. To get Zapdos you must lure pikachu to the egg sitting in the tunnel then play a pokeflute. If you did it right pikachu will hit the egg and he will shoot the egg out and the egg will blow up revealing Zapdos.
3. Articuno: As you come into the third section of the cave level, a zubat will fly around carrying a pikachu. If you hit the pikachu with pester balls or apples, the zubat will drop him and pikachu will deploy balloons for floating in the air. As you come to the articuno egg, the pikachu will trot over the egg and break it, revealing Articuno. You must wake up the Articuno with a pokeflute then articuno will fly pikachu to safety and you will have a sweet close up of pikachu on articuno's back.
Get Muk
In the Cave there are two grimers. Take lots of pictures of them. When the third appears near the three bulbasaurs, take a picture. Now throw lots of pester balls at him. He will evolve into Muk.
Ghost Photos
In the first tunnel, take pictures of the purple myst that floats around. When they develop you'll have a picture of Haunter.
Group of Charmanders
To find a group of Charmander, go to to the place where you can find the Moltres egg. The pelt the egg with pokemon food, and if you've recieved pester balls, throw those.
