"Mr. Big" (Freddi Fish)

"Mr. Big" is the mysterious main antagonist of the computer game Freddi Fish 4: The Case of the Hogfish Rustlers at Briny Gulch. His henchmen are Goby and Moray. Either of certain townspeople could turn out to be Mr. Big. Either "Mr. Big" just wanted to be a hogfish rancher.

Gil Barker
Gil Barker, who had previously been in Freddi Fish 3: The Case of the Stolen Conch Shell, was having a financial problem, explaining his gum sale.

Nelson Torso
Nelson had built a barbell in his belt buckle shop in an attempt to have the hogfish exercising. He meant to be a hogfish rancher because it seemed nobody would ever buy any more belt buckles from him.

Mr. Phil Fingers
Mr. Fingers attempted to help Moray lull the hogfish (to no avail). As a pianist, he wouldn't have made enough money for his family of 17 children.

Another one
He was sick of always traveling around.

Whichever one is "Mr. Big" is sentenced to doing hogfish ranch work with his henchmen.
