Hey, guys! Chatot here.

I just breeded my first Eevee, him who evolved into Umbreon, with a Ditto. His name is Dasher II. If you guys are playing Diamond and Pearl and are wondering where else to get an Eevee...

1. You can get one at Bebe's house in Hearthome, it's the house next to the Pokemon Center. Be wary, you can only get it once you get the National Dex*.
2. Once you get the National Dex*, you can go to Route 212, into the Pokemon Mansion (owned by Mr. Backlot). Go to the room to the right, you will see Mr. Backlot and his butler. Now save. And then talk to Mr. Backlot. He should say something like this:

"Er-hem! It brings me pride to have my garden at the back. Why bother traveling when Pokemon come to my garden ready to be caught? Well, aren't you jealous? Muhohoho, I bet you are! Well, I don't mind! I enjoy sharing my stories with you. So! Pokemon are always ready to see me. They sidle up, happy to see me. Well, aren't you jealous? Muhohoho, I bet you are! But I don't mind! I enjoy sharing my stories with you!"

Be aware that you need to say "Yes" when he asks you if you're jealous of his garden. After the second "Yes", he will tell you what Pokemon are available in his garden.

Example, "So! This is what happened when I visited my garden this morning. I saw a cute-eyed JIGGLYPUFF..." At this point, unless you want a Jigglypuff, you should soft-reset. To soft-reset, hold the R, L, Start and Select button together. It should restart the game. Keep doing this until Backlot tells you an Eevee is available to get in his garden.

Eevees are rare, just like the other Pokemon Backlot mentions in his garden. And it is only in Pokemon Diamond and Pearl you can catch an Eevee, otherwise you would've gotten one from an NPC, like Bebe.

If you don't want to go to Backlot to get an Eevee, what you can do is get a Ditto, which are also as rare - they can only be caught with the use of a Pokeradar. The Pokeradar will be received when you get the National Dex*. You can catch Ditto at Route 218.

After you get your Ditto, bring it (along with your Eevee) to Solaceon Town. Go to the Daycare center (the house with an old man standing in front of) and talk to the lady at the counter. She would ask if you would like your Pokemon to be taken care of. Say yes, and when she asks if you want another Pokemon to be taken care of as well, agree to it.

Now, to get your Pokemon to breed, just walk around and check back with the Daycare Poketch Application. You can get this by talking to the old man outside of the Daycare center. Wait until you see an Egg in the middle of the two and then talk to the old man again. He would give you the egg, only if you have an available slot in your party.

*National Dex. You can only obtain this once you've filled your Pokedex/Sinnoh Dex. Then talk to Rowan at Sandgem town, he will give you this and the Pokeradar.
