Pokémon FireRed and LeafGreen/Route 5

Route 5
Route 5 is a very small route that leads to Saffron City. It got tall grass areas which you can catch Pokémon in and it got the Pokémon Day Care which can help you raise weak Pokémon.

Day Care
Here, you can drop off Pokémon you don't want to carry along, but that you would like to grow nonetheless. You can leave undesirable Pokémon you want to evolve just to complete your Pokédex, or drop off your Magikarp and later on come back to collect a Gyarados. Alas, it's not free. You will be charged 100 for every level your Pokémon gained, but that's a small price to pay for what you get. Keep in mind that every step you travel outside the building gives the bred Pokémon 1 Exp. point, so don't leave a strong Pokémon here.

Underground Path
The building to the right leads to an underground path that skips Saffron City and reaches route 6. This route is full with items. However, most of the items there only apear after you obtain it from the Pokémon Center in Vermilion City. The little girl inside this building will trade for a. The traded Pokémon will be at the same level as the Pokémon you gave.
