With a pokeball.

Yes you can. Go to Route 205 South and use the Poke'radar. Keep trying until you find a Hoppip.
Skiploom can be accessed with 6 badges, in the Johto Safari Zone (same area as Hoppip and Sunkern.) The person who says "Skiploom is not there" is lying! I got Serebii and GameFAQs to back it up!
