Chucky Poo (Known In-game as The great mighty poo) is a big opera-singing, Sweet Corn-eating pile of sludgy fecal matter who appeared in Conker's Bad Fur Day and Conker: Live & Reloaded as the boss of the Sloprano chapter. His lair is the interior of Poo Mountain.
When Conker first entered Poo Mountain's interior, a Dung Beetle flew right into Conker; the Dung Beetle informed him that there was "something really bad" in the mountain. The Great Mighty Poo had taken the Dung Beetle's friends, Tezza and Bazza, and had killed them by dragging them into the liquid poo. Conker, however, in hopes of finding the alleged cash in the area, still ventures onward and meets some Sweet Corn. At that moment, the Great Mighty Poo orders anyone who is hearing him to bring him some Sweet Corn. Conker, not knowing where the voice originated from, does what he says and knocks out the Sweet Corn with his weapon, carries them to a platform and throws them into the center pool. In a parody of Jaws, the Sweet Corn is floating in the pool and looks around, followed by some unknown creature attacking it from below. After throwing in all of the Sweet Corn in the area, the Great Mighty Poo dramatically emerges from the center pool, places the last piece of Sweet Corn into his mouth to operate as a makeshift tooth, and begins to sing his song.
During the battle, the Great Mighty Poo will pull blobs of fecal matter from his body and hurl them at Conker. To defeat the Great Mighty Poo, Conker must use the three Context-Sensitive Pads to throw rolls of toilet paper into his mouth while he takes a break from throwing poo blobs to sing. Conker must throw one roll of toilet paper into the Great Mighty Poo's mouth for the first phase of the battle, two for the second, and three for the third. Upon the end of a phase, the Great Mighty Poo will disable the use of the Context-Sensitive Pad that Conker had previously used, forcing Conker to move on to the next one. Upon the end of the third phase, the Great Mighty Poo will sing an incredibly loud baritone note, causing a pane of glass inside the mountain to shatter, giving Conker access to a pull handle. Upon pulling it, Conker will cause the Great Mighty Poo to get "flushed" to death through the central pit, giving access to the Uga Buga chapter of the game.
