now this is a species of Pokemon i have not seen or heard about in quite a long time. i may be in college, but i hang around with certain people that still maintain interest in the classics and current Pokemon cards and games. i never did know what was so special about this one though other than it slept in the ground and you could usually only find it in that meteor cave in ruby or sapphire versions.
I remember it was one of the early swarms and you had to get the number of a hiker in a cave in crystal (the first pokemon game i ever had!) to even find it. Dunsparce is great.
One thing I can tell you is to avoid Kaisercraft or Kaisercard (i forget which it is). The textures don't look nearly so nice and the colours aren't as bright.
