The thirsty policeman on Pokemon platinum unfortunately can not be satisfied, and any item you have will not work, this was not created for a reason although it might have been before but been dropped by the makers. Sorry. He will remain thirsty forever... :)
you can get one from some Pokemon and from a man you don't battle talk to him he will give you a dawn stone
In Eterna City, (the town with the second gym) beside the Pokemon shop, there is a building, go in and talk to the old looking man, then he will let you rename your Pokemon.
