Actually, it is possible. If you have a link up cable for Gameboy or Gameboy Advanced SP AND a Old Old Old Gold or Silver version you are in very good luck. Because if you need a totodile or any of the starter Pokemon in that game for FireRed/LeafGreen you can use the link up cable to trade a Pokemon over to your Gold/Silver and get the starter Pokemon you need! you catch rattata and give it a rare candy and it transforms into cyndaquil
you have to trade cyndaquil to pearl to get it
You cant find one but you can choose Cyndaquil as your starter Pokemon.
Yes you can trade leafgreen version Pokemon to another leafgreen version.
It's a starter Pokemon.
you cant catch it you have to catch all 200 of the hoen Pokemon and professor birch will give you cyndaquil, chicarita, and todadile
You Dont
No, you cannot find cyndaquil in LeafGreen.
trade or hack i think?^^
No unless you breed the purified quilava from Pokemon colosseum OR get one from emerald/xd gale of darkness.
i think its talk to professor oak and he will give u cyndaquil,totodile or chikorita
..you cant but if your game version is leafgreen,, you need to have a firered and link it with leafgreen using a link cable and trade the Pokemon in a Pokemon center
Cyndaquil is a Fire type pokemon.
you need to trade from Pokemon xd using the game cube adapter!Or get the quilava from Pokemon colosseum and put it in the daycare with a ditto and hatch the egg you will receive and boom its cyndaquil.
You cannot get Cyndaquil in Pokemon Red. It is only on Pokemon Silver, Gold, and Crystal.
you have to trade cyndaquil to pearl to get it
You can find Cyndaquil at Mount Stark on Pokemon Diamond.
You can get cyndaquil three ways, One get the quilava from Pokemon colosseum, purify it then trade it to sapphire or leafgreen then breed it with a ditto when its a typhlosion then hatch the egg and its cyndaquil then migrate the cyndaquil into platinum, Two get a cyndaquil from Pokemon xd gale of darkness by going through mt battle while using two Pokemon for the entire thing so i.e if you have latios and latias at the first battle for the rest of the 99 battles you need to keep latios and latias. After beating mt battle you should be able to pick a johto starter and you will pick cyndaquil, Three get a cyndaquil from Pokemon emerald after totally completing the pokedex and then talk to prof birch and he will let you take one take cyndaquil. The first and second way are easier but if you can manage to do the third one nice job.
