Dratini evolves into Dragonair at 30 and Dragonite at level 55
It takes time but definitely worth it
Trade dratini from firered or leafgreen to ruby.
You cannot find or catch Dratini in Emerald. You can trade it over from FireRed or LeafGreen.
You can catch one in Pokemon Firered and Leafgreen. But you can only catch one in the safari zone or you buy in celedon city
you can evolve it from a dratini at lvl 30 i believe (not sure). if your lucky you might find one fishing in the safari zone with a super rod. you can also get dratini's there but there both really rare and hard to catch.
Sorry but only firered and leafgreen can get dratini you must trade one to sapphire to have one.
Its super easy to get one, you only need 1 link cable, Pokemon firered or leafgreen that can trade Pokemon to ruby, Sapphire and emerald and a dratini. If you don't have a dratini at Pokemon firered or leafgreen, you have to look at www.serebii.net and look at poke-earth or the pokedex. I hope it helps!

You get a houndour then evolve it i will update when I find out where to catch houndour
Evolve Eevee by exposition of a Thunderstone.
NO,you will have to trade it to evolve it.
first buy a dratini from the celadon city in the game corner. then evolve it.
To get dratini you can either get one by getting lucky from fishing in the safari zone or get it as a prize in the casino.
