You'll need the SecretPotion from Cynthia at Valor Lakefront I believe.
Dimond and Pearl Dimond and Pearl Dimond and Pearl Dimond and Pearl
You get the potion from Cynthia at Valor Lakefront. Then go to route 210 where the psyducks are.
The Psyducks are right above Solaceon City.
good question because if you have the secret medicene or whatever that cinthia gave u then use it on them.
you go to lake valor, where you'll meet the Pokemon master Cynthia. she'll give you the secretpotion, which you spray on the psyducks to get past them.
After you have defeated leader wake in pastoria city, Cynthia will give you a secretpotion, go to the psyducks and they will go away
Can't.
In Pokemon Pearl, the player must get the SecretPotion from Cynthia to clear a pack of Psyducks from the route that leads to Celestic Town. This is the only way to proceed forward.
get dimond or pearl its funner
none of your business
a cool Pokemon game
If you mean the Psyducks blocking your way in Pokemon Diamond/Pearl/Platinum, they're on Route 210. ..However, you need to specify the game to get a precise answer.
