I've picked Pokemon Black and White back up again when I realized that the second one was coming out and I actually haven't finished the first one yet, and so I'm doing a little level grinding and had forgotten how much I love Audino, unfortunately I love them for all the wrong reasons, but they're pretty dang awesome! SO MUCH EXP! But alas, this tends to sadden any fans of Audino while I'm around them, especially Lauren. I'm so sorry... I can't help it... they're just worth so much EXP!
Yeah, they're a little hard to come by, but they're totally worth it! I once battled one and sorta felt a little guilty, just before it fainted and gave me a truck load of EXP, it actually healed my Pokemon... I was touched.
