Contests
As you might have noticed, (if you have the game) contests are different in diamond and pearl. Each contest goes through 3 stages:Visual: Dress up your Pokemon to match the theme the judge chooses. I always find this fun. Especially dressing up a pokemon like Palkia. XD
Dance: After the visual part you go through a dance competition. Try to copy the steps the leader does, and when you?e the leader you get to decide the 3 steps. ^^ Also the leader pokemon dances with whatever you dresses them up with still on them.
Performance: Of course if you've played ruby, sapphire or emerald you should be familiar with this part. This is the part of the contest where you show off you moves! Make sure to use moves that are the same as the contest you entered! (Cool moves for cool contests, etc)
