Can slowpoke be holding a kings rock in the wild on Pokemon pearl?

Slowpoke cannot be holding a King's Rock in the wild on Pokemon Pearl and instead maybe holing the Lagging Tail item. However wild Poliwhirls now have a chance of holding it King's Rock. Wild Poliwhirls can be found in Route 225 with the Super Rod or on Routes 227 and 228 by Surfing. Alternatively if you have a Pokemon with the Pick Up ability and at levels between 11 and 30 it has a 1% chance of picking up a King's Rock.
