Route 4 (West)
The Magikarp Salesman
A Pokémon Center stands near the entrance to Mt. Moon. Inside, a shady man offers to sell you a Magikarp for $500. The fish is nearly useless until it evolves into the powerful Gyarados at level 20. With enough money to spare, you can end up with a strong Water-type Pokémon sooner than normal, but you can soon hook a Magikarp for free with the right fishing rod.

Follow the winding tunnel in a clockwise direction to the northwest, where a Super Nerd claims both the Dome Fossil and Helix Fossil lying here as his own. Defeat him, and he lets you choose one of them for yourself. The Dome Fossil was once a Kabuto, while the Helix Fossil was once an Omanyte. Go west to the final stairway and you are ambushed by a pair of Team Rocket Grunts. They intend to steal the fossil you just acquired, and draw you into battle.
