I have a few questions:
1: What are the best moves to teach Quilava?
Typhlosion @ Leftovers/Petaya Berry
Trait: Blaze
Timid Nature (+Spd, -Atk)
- Fire Blast/Flamethrower
- Substitute
- Sunny Day
- Thunderpunch
Not as good as Charizard, but decent. Well, as far as crappy Fire-types go.
2: Where do I find Sea Incense (On Fire Red)
From the entrance to the Lost Cave go right, up, down, up. From the entrance go right and down for the Lax Incense.
3: What is a good way to prevent sleep in battles? (Something that won't take up a turn)
There are a couple things that will work. The first is to have a Poke with the Insomnia Ability. That prevents the Poke from even being put to sleep. The following Pokes have the Insomnia Ability:
Shuppet
Banette
Murkrow
Spinarak
Ariados
Drowzee
Hypno
Hoothoot
Noctowl
You can also have a regular Poke hold the Chesto Berry or the Lum Berry, but that will only work for one turn.
4: Where is a good place to level pokemon after they reach about level 40?
Seven Island, if you have gotten that far. There are Pokes there in the 40s and trainers have Pokes in the high 40s that give you quite a bit of Exp Points. If you are not that far than you can go through the Weak5 over and over, as long as you don't go talk to Prof. Oak and get the National Pokedex. Those are the best places.
5: How many Rare Candies are there in game?
Honestly, there are limitless amounts of Rare Candies, if you have a Poke in your team with the Pickup Ability. After a few battles, check that Poke and see what they have picked up. I believe there is a 5-10% chance it will be Rare Candy. As for stationary RC opportunities, there are nine that I have found.
