You can't unlock Petey Piranha in Mario Kart DS. It is myth character, and you could probably only obtain him if you Sprite hacked and made some manual changes on the game.
The four chanarcters which you can unlock on Mario Kart DS are Daisy, Dry Bones, Waluigi, and R.O.B.
You can also obtain Shy Guy from hacks.

No. Petey Piranha is only in Mario Kart: Double Dash!!.
You can't get R.O.B or Petey Piranha on Mario Kart Wii, but you get Toadette by "Playing on all 32 courses in Time Trials mode or winning 1,000 Wi-Fi online matches." You don't have to unlock the Koopa Troopa. He's already there!
