Cow Skull

The Cow Skull is a character in the game Skull Dude who serves to liven up the world and essentially be a flavour NPC that the player can converse with to pass the time, similarly to S.U.E.

The Cow Skull makes a cameo appearance in Skull Dude 2, appearing in the only patch of grassy ground in the game.

According to the Cow Skull, he has a whole body submerged under the marshy soil of the swamp, with only his head emerging, which is why he appears to be a simple disembodied cow skull. This carries over to Skull Dude 2, where The Computer transported the Cow Skull into the drone's memory along with the entire chunk of earth around it to preserve it's entire body.

Skull Dude
Skull Dude initiates conversation with the Cow Skull with "How's it going?" each time, for context.
 * "...Ok"
 * "I saw a bird once. Have you seen any lately?"
 * "...Ok. Again."
 * "My feet fell asleep. And them being underground isn't helping the situation."
 * "Another bird showed up. It was different. It seem[sic] to disappear when I looked at it."
 * "I was thinking about buying a hat. Have you seen one at the Junk Shop?"
 * "zzzzzzzzz..."
 * "Ok. A bit warm, but that's the swamps."
 * "Ok. A bit warm, but that's the swamps."

Skull Dude 2

 * Skull Dude asks the Cow Skull if The Computer let him keep his body, or if he's just a skull: "Nope, I still got my body. The Computer just migrated the entire area around me."
 * "This place is strange. I miss the swamp."
 * "I don't hear the bird anymore. I hope it made it in here with us."
 * "I saw the bird again! It did make it!"
