Blackmail Iguana Bob

Blackmail Iguana Bob is an unmarked quest in Fallout.

Detailed walkthrough
Although Iguana Bob does business in the Hub, this quest starts in Junktown, where the entrepreneur's supplier resides.

Visit Junktown hospital, climb down the ladder into the doctor's basement and meet the mentally-challenged dwarf worker Gretch. He will not so subtly let slip about being hard at work sorting out some human body parts to send to Iguana Bob in the Hub. It is then quickly realized that there's more to Iguana Bob's iguana bits than meets the eye.

If the Vault Dweller confronts Doc Morbid over it, nothing will happen, and they cannot tell the authorities. Attacking the doctor will prompt his two bodyguards, Flash and Cougar, to defend him. Killing the bodyguards has no repercussions. Killing Morbid will result in a loss of -1 reputation.

The Vault Dweller then needs to go to the Hub and find Iguana Bob's stand downtown. A high Speech skill is needed to intimidate him, and depending on one's Barter skill, Bob can be blackmailed for a large slice of his profits.

Rewards

 * 500 XP
 * A share of Bob's weekly income, depending on the price that was bartered for.
 * -2 Reputation per deal made.

Behind the scenes

 * When trying to blackmail Bob into paying the player character, one of the dialogue options is to scream "Prime Choice Select is made of people!!!! It's made of people!!!" This is a reference to a line from the film Soylent Green.
 * Along with this quest, it would also have been possible to report Iguana Bob to the Hub police.
