Pokémon FireRed and LeafGreen/Route 3

At the entrance to Route 3 you will meet Prof. Oak's Aide, who will give you the Running Shoes. Now you'll be able to run fast by pressing . There is a Pokémon center at the end, so don't fret about returning to Pewter City constantly. However, make sure you're well stocked up on potions before attempting Mt. Moon.

Don't waste time looking for both forms of Nidoran on Route 3; depending on your game, you only have a 1% chance of catching the rarer form. (Female in FireRed, Male in LeafGreen.) Your best bet to get both forms is to catch two males in FireRed, or two females in LeafGreen. On Route 5, you'll be able to trade the extra one with an NPC for the other gender. Regardless of gender, both Nidoran's will later evolve into powerhouses, so catching at least one is very recommended.

#29 Nidoran♀	#32 Nidoran♂
Nidoran is the first true Poison-type Pokémon which can be caught in the game. Nidoran can be quite an ally throughout most of the game, and even onto the end. Its Poison Point ability is quite useful: when an opponent touches Nidoran, the opponent may become poisoned. Its final form is Nidoqueen, a Poison/Ground-type defense-orientated Pokémon, that will appear only after you use a Moon Stone on it.	The male form of this poison Pokémon. It is much easier to catch it in Fire Red; Leaf Green players may want to wait until the Safari Zone to catch it. It also has the Poison Point ability, and possesses a more varied moveset than its counterpart. Its final form is Nidoking, which is a Poison/Ground-type offense-orientated Pokémon, that will appear only after you use a Moon Stone on it.
#39 Jigglypuff
The well known balloon Pokémon whose singing lulls everyone hearing it to sleep. This can be helpful in catching Pokémon. It evolves by using a Moon Stone into Wigglytuff, but when evolved, it will not learn any more attacks by leveling up. Its stats and movepool aren't very impressive, so using it isn't recommendable.
