hint: you can also stack this with a shiny cheat.
hint2: there are glitches with this code to catch 3 different glitch pokemon. (save before
you catch them)
1. number 0: it has no name, is invisible, shines like a shiny pokemon, and sounds like
bulbasaur. throw out all the items in your items pocket then use the cheat with 0 items.
if you put him in your pc he disappears, if hes in your party he may delete your pokemon
if you put one over him.
2. egg: have 494 items in slot 1. he will freaze the game upon catching
3. bad egg: have 495 items in slot 1. he will freaze the game upon catching
if you have over 495 in slot 1 the game will freaze when you encounter the pokemon because
it doesnt exist.
