Why did Pelipper came up in my PokeRadar-scanned grass on Route 230, Platinum?

Question

I found a Pelipper in a shaking PokeRadar grass. As far as I know, you can only find Togepis from PokeRadar grasses in Route 230, right?

There's only a 22% chance to get Togepi with the Pokeradar, so the other 78% must be for the other Pokemon you can normally find on the route.

Answer 1

According to here, Pelipper appears in the normal Tall Grass on Route 230 with a 30% chance to appear. The Pokeradar does not only make the special PokeRadar Pokemon for that route appear, (in this case, Togepi.) There is only a 12% chance for Togepi to appear while you are using the PokeRadar.

Hope I could help!
