Go through the gate way at the left side of Jubilife City and talk to the fisherman!
Sorry, but Entei can not be obtained in Pokemon Diamond and Pearl itself, you must transfer it from old GBA games and use the Pal park in DP to catch him.
In Pokemon Diamond/Pearl, you find a old man at route 212 with a Leafeon.
Go to Eterna City and talk to an old man called The Underground Man in the house next to th Pokemon Center
The old chateau is in diamond and pearl
10 years old
the old chateu is only in Pokemon diamond pearl and platinum versions
no its only the old Pokemon ranger and diamond and pearl
You can not get a shovel in Pokemon Diamond and Pearl. But you can get an explorer kit to dig underground in diamond & pearl. To get a explorer kit you go to Eterna City and go to the house next to the Pokemon center. Talk to the old man in there and he will give you a explorer kit.
