I have Balm Mushrooms, a Comet Shard, and Pearl String, and none of them interest him. I picked up a ton of crap from the Abyssal Shrine, but they were all bought up by the dude in the mansion nearby.
For that matter, who WILL buy the crap I mentioned, as it's doing nothing but wasting space? --- An infant sea turtle is actually capable of killing an adult African bull elephant. It does, however, require a substantial amount of surprise.
The Balm Mushroom is for the maid on Route 5, the other 2 are for the guy in Icirrus City PokeCenter, by the counter. --- Wii FC: 0967-4933-7285-7961 (BlkThunder) Pokemon White FC: 3611-0312-2067 (Sid)
I believe that specific maniac wants Rare Bones. Don't quote me on that though. Does the guy have a karate sprite?
Also, the maid on route 5 will buy any food type items (berries, big/small/balm mushrooms) for either really high prices (25,000 for the BalmMushroom I think) or double what a Mart would buy em for.
Same for the guy in the 7th Gym town except he wants "ore" (basically any stone or gem type object such as Evolution Stones or Nuggets or the new Jewel things) --- Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost.
