If not for all the Pokémon trainers waiting around to duel, Routes #14 and #15 might almost be relaxing. Oh well, a trainer's work is never done! Like Route #13, these routes have their fair share of trainers, so be prepared. Every battle you enter makes your team stronger and brings you one step closer to becoming a Master Trainer.
The TM 20 near the end of Route #15 just contains not-so-useful Rage skill. But if you speak to Professor Oak's assistant at the lookout station between Route #15 and Fuchsia City, he will give you the EXP.ALL if you've collected 50 different Pokémon. This rare item allows you to share experience points with Pokémon that don't fight in battle.
Once you've managed to snag the Super Rod in Route #12 and HM 02 (Fly) in Route #16, you'll be able to fish up pretty much any Water-type Pokémon you want... Even a Gyarados (appearing occasionally in Fuchsia City) in the Yellow version.
Note that you can get a Psyduck in Yellow... Just not by fishing. Use Surf to walk around in the pool at Route #6, and one will appear. Shellder is one water Pokémon that you won't want to miss, but he's also hard to track down in Yellow. Try Route #18, just outside of Fuchsia.
|#132 Ditto||#60 Poliwag|
Ditto is fun as a novelty, but worthless in combat. He only knows one skill, Transform, which he can use to make himself a mirror image of his opponents. The only problem is that he keeps his own low stats, so the original will trounce him nine times out of ten unless you're extremely skilled.
Water-type Poliwags evolve two times: Into Poliwhirl at level 25 and into Poliwrath with the aid of a Water Stone. At that third stage of evolution, they gain Fighting-type characteristics, but once again their inability to learn any Fighting-type techniques makes this more of a liability than an asset. Certainly not one of the better Water-types.
|#90 Shellder||#120 Staryu|
Like Poliwags, Shellders evolve into their higher form, Cloyster with the aid of a Water Stone. And like Poliwags, they gain a new type in the process: Ice. But very much unlike Poliwags, Shellders are worth using. They're incredibly strong on defense and have a high enough Special to make use of their powerful Water and Ice attacks. Just don't use that Water Stone until at least Level 30.
Staryus also evolve with a Water Stone and also gain a second type, Psychic. The evolved form, Starmie, has a really high Special, so it could make good use of its Psychic abilities... If it had any (besides Light Screen, that is). A good Pokémon, but only if you're willing to use a lot of TM's to teach it Psychic skills. Blue/Red players can catch their own in Routes #19 through #21.
