Pokémon FireRed Easter eggs

Fast daycare exp
This cheat works for all Pokemon games that require steps to level up your Pokemon in the daycare
First deposit the Pokemon you want to level up
Next go to the nearest place that pushes you back if you can go past it like the sand area or sand ramps in ruby Sapphire and emerald, I advise you using the fastest transportation in the game you have fire red leaf green use water falls or the bike path with no bike. I advise waterfalls with all of them because it takes a while to get it finally tape down the button direction your moving in. Make a rolled up thing of tape put it on the button tape it around the game system and turn off the screen light if you have one and let it sit all night and a low level Pokemon would have grown at least 10 levels just make sure you have enough money to take your Pokemon back
