I did something similiar but water pokes can handle bout any type.
They can learn Ice beam/blizzard-Earthquake-some learn dark type moves.
And Lanturn is half electric.
Do normal types as a challenge.
They can learn multi-type attacks but they usually have low defense/special attack and they do not get bonus' added to diff type attacks.

I started once a normal-only pokémon challenge, were you could only have a Pokémon once (2 Sorlax, 3 Ratatas, etc isn't allowed). Use your starter only to beat your rival and catch a Ratata, and then release it. Then you have to stick with that Ratata all the way to Mt Moon until you catch a Jigglypuff and a Clefairy, etc. Beating the first gym is hell though... It's interesting because there are actualy few normal-only pokémon... never got to finish it though because my save was deleted and I didn't feel like going through all that Ratata training again

Only pure normal Pokémon count, so you're better off doing this on a Blue version so you can use Persian.

Didn't do it with normal cuz of snorlax that thing is uber in fire red story mode lol.

Oh not to mention Tauros + Khangaskan ( w/e its spelled ) chansey that's 3 right there that can get you past the league lol.

Then that's a challege ^^

Eevee (obv unevolved)
snorlax (one)
jigglypuff
clefairy
Lickitung
And pidgeot (Yes, he's flying but he's half normal too. and fly is nice unless you like biking around)

no, no... they must be copletely normal, no hybrid types. These:

Rattata
Raticate
Clefairy
Clefable
Jigglypuff
Wigglytuff
Meowth
Persian
Lickitung
Chansey
Kangaskhan
Tauros
Ditto
Eevee
Porygon
Snorlax

If you use a water/flying one to surf/fly you can't use them in battle, leaving you a set of only 5 Pokémon

Like I said. Pidgeot isn't a strong pokemon, I just would want one to fly.
I could deal with 5, shrug. The bike in early versions suck in terms of speed.

Oh, I misunderstood you. Yeah, a set of 5 is enough... in fact I think a team with Snorlax and two of either Persian, Raticate or Tauros, sounds like it can do the job.
