Jigglypuff Purchase in Pokémon Center: Magikarp		Sandshrew Purchase in Pokémon Center: Magikarp

After you receive the Boulder Badge, other Pokémon trainers will see you as a worthy opponent. No fewer than eight trainers wait to challenge you along Route #3. You'll have a tough struggle getting through them all, but you'll emerge from Route #3 a more powerful (and richer) trainer than ever. Stock up on Poké Balls to capture some more Pokémon in the wild too.

On the way to Mt. Moon

There are eight disgruntled Pokémon trainers between Pewter City and the entrance to Mt. Moon, but they're pretty easy to avoid (by staying out of their direct line of sight). Still, you may need the EXP: Mt. Moon is tough.

At the Mt. Moon Pokémon Center, you can pick up a black market Magikarp for 500. As for wild Pokémon, Jigglypuff are only decent in Red or Blue, but Yellow players shouldn't move on without a Sandshrew in tow.

#39 Jigglypuff	#27 Sandshrew
Jigglypuffs, even more ridiculously cute in Yellow, have a ton of HP, but pretty low in all other stats. Their Sing attack is annoying to be put to sleep by, but is nearly a coin-flip in accuracy. Pound works well enough early on, but Jigglypuff will be hurting for good attacks until it learns Body Slam at level 34. Jigglypuff can use a wide variety of powerful TMs, but it probably isn't worth the use of precious TMs, as the result isn't spectacular. Jigglypuff can evolve right away with a Moon Stone, found in Mt. Moon, but this will disable it from learning moves from leveling up.	This Ground-type Pokémon doesn't learn anything particularly exciting on its own, but has decent Defense and Attack scores, while not giving up too much Special and Speed. The lack of a Rock-type means that it can at least survive a medium power Grass or Water attack if it must take a hit. While it must use a TM to grant it a Ground attack, Sandshrew isn't that bad as a Ground attacker.
#129 Magikarp
The thing about Magikarps is that they're totally, completely horrible. They come with only one technique, Splash, and it does absolutely nothing. Magikarps can't learn any TMs or HMs and they don't even learn a real attack until level 15! BUT if you can get one to level 20, it will evolve into Gyarados, a Water/Flying-type with great stats and a decent move pool. If you want, you can buy it to begin leveling it up now. However, this will devour many experience points that would have gone to other Pokémon at this early stage. You can fish for a Magikarp anywhere some other time once you get the Old Rod.
