Route 5

Now that you're on the other side, go south, and you'll find a house. That's the Day Care Center. The old man inside will raise your Pokemon's level ($100 for each level) if you leave it with him. The only bad thing is that your Pokemon might learn some unwanted moves, and delete moves that you want. The good thing is, if you were to leave a weak Magikarp with him, and walk for a while, it'll be able to evolve in no time into a powerful Gyarados! After finishing the buissness with the Day-Care, go south. The entrance to Saffron City is closed, so you'll have to detour through the Underground Path to the next route.

Before entering the Underground Path, talk to the little girl if you want to trade your male Nidoran for her female Nidoran. You'll walk a long walk in the dark Underground Path. Soon, however, you'll see the light of Route 6.

Route 6

Route 6 has six trainers waiting to fight but you can get away with fighting only one of them if you want. However, once again it is recomended that you battle all the trainers. There's a lot of grass but no new Pokémon. Head to Vermilion City since once again the entrance to Saffron City is closed. Go all the way south, and you will arrive at Vermilion City.
