Daisy, Mavis and Olive

"Oooh! It's like the screaming shits, it is!"

- Marta

Marta is the first cow seen in the Poo Cabin's grassy field with Bugger Lugs. She appears in Conker's Bad Fur Day and its remake, Conker: Live & Reloaded. Her friends are Mavis and Olive, who look identical to her. Marta is known to talk to herself a lot.

History
After Conker tricks Bugger Lugs into hitting a target, the wooden shaft opens, and Marta walks out. She decides to eat some of the grass. After Conker rides Bugger Lugs and rams him into Marta, she gets angry at Bugger Lugs and loses her appetite. She decides to drink some Prune Juice.

Marta goes to the Prune Juice and notes how it looks "cranberry flavored". She drinks it and deems the taste as "a bit odd". Suddenly, the Prune Juice gives her diarrhea (which she calls "the screaming shits"), and she unhappily runs off to the grate and continues pooping down it. She hopes that her friends, Mavis and Olive, do not notice.

Later, while she is still pooping, Conker knocks Bugger Lugs into her, which kills her. Her guts and blood fly all over the place, similar to Marvin's death in the Barn Boys chapter. Marta and her two friends, Mavis and Olive, cause the Poo Cabin to flood from their excessive diarrhea, regardless of how long or how much they poop.

A cow, possibly Marta, is also briefly seen on a milk carton in the cutscene where a Weasel Guard brings Milk to the Panther King. The image is printed on every side of the carton, with the caption "Fresh 'n' white" below it. In the Game Over sequence, it is only on printed on the left side. In Live & Reloaded, the cow is only printed on one side, but is now captioned "Mavis". This strongly implies that the milk originated from said cow. This side of the carton is unseen during one of the Game Over sequences.

Mavis and Olive
Mavis and Olive are Marta's friends. They are essentially the same as her, as they both eat grass upon entering the grass field, losing their appetite, and drinking prune juice after Conker rams Bugger Lugs into them. They are both also killed when Bugger Lugs hits them as they both also poop down the grate.

It is unknown which of them are respectively the second and third cow. The only difference with Mavis and Olive is one of them (the second cow) must be hit twice for her to lose her appetite, whereas the third cow must be rammed into three times. In Live & Reloaded, both Mavis and Olive only have to be rammed into once, like with Marta.
