Question about Pink Bean quest.

 Spoiler

He keeps coming this far but it won't let him finish the quest. The quest log says that all he needs to do is come in this room.

He's tried clicking around, hitting random places, and nothing is working.

He's done this twice, both yielding this result. The first time, the NPC said he's on the wrong channel. The second time, he asked him to form a party, but said he need 3 people to start the expedition. He's annoyed and doesn't want to waste any more money buying masks to try and finish this quest.

Any ideas as to what he should do?

I still haven't finished the mask quest yet, but isn't the quest after the chaos marble the equivelant of the Nine-Dragon's quest in Leafre (meaning you'd have to kill Pink Been)? Correct me if I'm wrong, because I thought the chaos marble was the last quest before Pink Been related quests.

Harrison's wasting his money. You need to kill Pink Bean to finish that quest. And if my word isn't taken, how'bout StrategyWiki?

Right, so you gotta kill Pinkachu. That's all he wanted to know. And he doesn't buy his masks, he hunts them XD
