Bob

Biography
Bob was dead before the party ever met him. His body was found in the Goblins' cave while the party was working for Mining Co.. The missing scout was found injured in the same cave and had apparently met him in the forest a week prior. The scout did not know him before that point.

Later, when the party visited Mine No. 4, someone perfectly resembling Bob told the party not to worry about Marcus or Nemo taking too long in the mine. It wasn't until a few hours later that Ragmesz noticed the resemblance and a rescue mission began. This version of Bob had been a puppet created by the ooblex in the mine.

It was later learned that Bob used to be the foreman at Mine No. 4 and did work for Mining Co. before he died. Before his body was identified, it was not known that he was missing. The identification of his body was what led the rescue crew to travel to Mine No. 4.

While it is not explicitly known what happened to Bob in the lead up to his death, it is likely that he was attacked by the ooblex at Mine No. 4. He then ran away and was captured by the goblins. It would have been at this point he met the missing scout. During their time together, he succumbed to his injuries or was killed by the goblins.
