RE: Awesome Tricks and Screenies to prove them
Did you know that you could get a Pokemon named Mewth in Gold and Silver? It's a fusion of Meowth and Mew.
First, catch a male Meowth and nickname it MEWTH. Go to a Pokemon Center (or the Pokemon Day-Care) and perform the cloning glitch on that Meowth, but turn the game off before it says "Saving." If your timing was just right, when you turn your game back on and look in your PC, the Meowth will have be lv.0, have no name and will be female (this is called a Bad Clone). After you have accomplished this, save the game.
Next you need to get a Pokemon that know Slam as its 3rd attack (Sentret is a common choice) and nickname it MMMMMEW. Make 4 normal clones and a Bad Clone of this (you should have a total of 5 normal Sentret if you do this). Withdraw all of the normal Sentret, followed by the Bad Clone.
Give the Bad Clone to one of the Day-Care people and take it right back. Move the Bad Clone to the top of your party. Select Move Pokemon. Move one Pokemon that you don't care about to the top of your party. No, you haven't missed anything; you will have 7 Pokemon. You should notice in the Move Pokemon screen that your party is empty. The glitch at the top of your party is confusing your PC, and all Pokemon below that glitch are invisible. Give the Bad Clone back to the Day-Care person.
Go back to the PC and deposit the first Pokemon in your party, followed by the first four Sentret. If they are holding mail, you will have to remove it before you can deposit them. You should notice several things now: first, the names are shrinking by one letter each time you deposit a Sentret. This is the reason for renaming the Sentret back in the beginning. Second, All of the Sentret should be level 0.
Take back the Bad Clone again. Give them the Sentret and immediately take it back. If you look in your party, you'll have a Mew.
Withdraw the remaining Bad Clone from the Pokemon Day-Care and give them Mew. Go to your PC and get the Bad Clone of Meowth you made earlier. Give it to the other Day-Care person and immediately take it back. Check your party and it will have transformed into Mewth!
Mewth is the Fusion Pokemon. It it the same size and weight as Mew. Mewth knows Pay Day, Scratch, Psychic, and Twister. It can't be taught all TMs and HM's like Mew, but it learns the HMs upon level-up.
Is this proof enough for you?
