Pokemon Leaf Green

i dont play pokemon but i did find this information on it...

-Really easy level ups
Okay, you know how when you leave a pokemon in day care it gains 1 exp for every step you take, right? Well, if you can get to a waterfall (Or mudslide in R/S/E) put a poke in day care and have you character face the waterfall. Then find something to hold the Up arrow down. A rock, or whatever. Then go to sleep, watch TV or do whatever. Your character will keep trying to go up but falling down, and you will gain EXP for each step.

i found the information at:

i hope it helps!
