Yes, they will alert you and say, "There seems to be an interesting Pokémon in [Kingdom's Name]!"
You can link with it.
No, but if you have a girl or a ditto you can breed it and get more eevee's.
To get more than 1 Eevee on Pokemon platinum you can migrate some from a Pokemon GBA game OR get a Ditto and breed it with your Eevee. The final way is to use an action replay/gameshark to find some more. The codes for an action replay can be found at www.codejunkies.com
Breed in the daycare with ditto
If you breed Eevee you can get Eevee eggs, but otherwise, no, you're only given one Eevee from Bebe in Hearthome.
Breed eevee with a ditto. This works for both male and female eevees, although if you are lucky enough to own a female eevee then there are other Pokemon you can breed it with. Check http://www.serebii.net/pokedex-dp/133.shtml for a list
yes, it is a mansion Pokemon well you can also breed it at the daycare with a ditto, then hatch the egg
first you need: national dexdittoeevee or any of the eeveelutionsfirst put eevee and ditto in the daycarethen get the eggand walk about 8900 steps and you will get an eevee
Yes, once you beat the elite four you can breed it.
You must breed evee or an evolution of it at the breeding place on four island.
You have to find a Ditto and put it in the daycare centre with an eevee or one of it's evolvee's to get eevee eggs :)
Shinx-luxio-to luxray Dialga,Staraptor,eevee,Jolteon,Darkrai i name all there`s more than 300 Pokemon! get the Pokemon diamound book you can find it at BlockBuster
(Note. Have to defeat pokemon league first and help Bill's friend to get the 2 gems)you can get more than one eevee, but you have to get one first, which is in the back of the pokemon mansion in Celadon City. After you get the eevee you go to Route 15 and walk around in the grass for a while, and with luck, you might find a ditto there and catch it. When you catch the ditto go to island 6 or 7 or 8 i forgot which and there will be another day care centre there and you put the ditto and eevee with them, come back in another day and they will give you an egg with your 2 pokemon. Hatch that egg and there will be an eevee inside. Working. I've done it myself
