it means that the pokemon will take a while to find by that i mean its super rare to find in that area. (iv got same problem)
look the Pokemon you whant up in the pokedex click on the check pokedex click on area go to the spot that's flashing red and capture the Pokemon your looking for. hope that anseres your qestion if not put a mesage on my bord
it's either a cave or the area of a shiny Pokemon
In Pokemon platinum you go to the survival area next to the pokecenter[red top]in the house.
When you look in the PokeDex into the Bellsprout entry, it says: Area Unknown. That's because likely this Pokemon can not be caught in this version of the game. You might need to trade with Leaf Green.
if you own a Pokemon lets say magikarp the red areas on the map on the pokedex are where you can find it.
Nope.
you fill your pokedex
That means that is the area where you can find the Pokemon so for example if its shows red at a route to the left of sunnyshore city then go to the route to the left of sunnyshore city to find the Pokemon your looking for.
a pokedex?or a pokeball?
catch em all!
you get to fight ash, but he apears as pokemon trainer red.
