An Abs-olutely Abs-tract Ab-venture
From A KoL Wiki
You sneak around the Toy Factory, avoiding the animelfs and their creepy giant eyeballs. You see one of the animelfs left his lunchbox under his work station, and open it.
There's a recreation of the entire first level of Jackass Plumber in there, all made out of food! Another animelf walks up while you're admiring the workmanship. "Hey, is that your lunch, ha ha? I'll trade you for it! I mean, I already ate my lunch, but you can have these detailed schematics of the abdominal portion of our giant mechaelf, ne?"
You make the trade and bring the schematics to Uncle Crimboku.
Occurs at Crimbo Town Toy Factory (2012), on your 300th adventure in the zone.
