Raise Your Monsters to Level 100
To make your monster Level 100 Go to the 7th item in your Tools. Hit select. Get into a fight. Hit select on the attack you dislike. It will change. (Note monster must have all 4 attack spaces filled.) Win the fight. Monster will become level 100 and will go to the next stage of it's life (if it has one.) Note: that it will not change if you use a Stone to make it change.
There are 5 abilities that you can teach your monsters. (Note: I translated these from Japanese.)
1. Cut. In Kuchiba City there is a ship. If you have visited Masaki's then you have a ticket. Get on board and get to the captains room you can get the first ability. It is a very bad a attack.
2. Flash: Go through the tunnel where all those moles are. At the other end you can get the 5th ability Flash IF you have 10 monsters. This is used for only lighting up a tunnel that you will only have to go through once.
3Surf: in Sekichiku City there is place called Safari Zone. Fallow the arrows till you get to the Treasure House. You will get the third ability. You can now swim.
4. Strengh: near the Treasure House you can the Gold Dentures. Give them to the guy in the house across the road to the left of the Center. He'll give you the 4th ability. When I say left I mean the left of the gameboy. You can now push the rocks like the one in his house.
5. Fly: near the Kabigon in Tamamushi there is a bush. Cut it down, go through the gate and into the house. There will be a girl. She'll give ya' the 2nd ability.
To get all 150 monsters you must have the blue and red version of Pocket Monsters. Now play through the game till you find your first monster. Now go to the field with the Charmanders and capture 1 of them only. Now plug in your game link to the other version of the game and press trade rapidly until you hear a tone. Look at your monster collection and you will have all 150 monsters!
Get Mew
To get Mew, go to Shion Town and ask the nickname changer to change your Koiking's nickname to Mew. Go into your tools, go down to the 13th tool and click SELECT at least 8 times. Now ask the nickname changer to change the Koiking's nickname again. The monster will blink, the changer won't do it and you have Mew!

You should use the MASTER BALL! But if you have a really strong guy like Laplace with a high Level then you can use an UltraBall.
8. Omnight or Kabuto: remember how in that cave after the first boss you got one of two fossils. Well, in Glen Town you can give some guys in the building next to the Center. Go out and go back in and they'll give you either Kabuto or Omnight. It all depends on which fossil you took.
