Hmmmm.. the peaceful remedy, of pancake barking, longing for his dead owner... 
Yellow thought, sipping his coffee. He didn't usually drink coffee, but being in his shoes would've been enough to make someone off themselves, out of fear.

"Well, Panny, time to go for a walk." He said, while leashing the (ferociously) growling canine. He opened the door to see Red roaming the hallways with his cat. Pretty surprising, but the last dead body found was over a month ago. Even though nothing bad has been happening, Orange, Lime, Black, Yellow and Red decided to trust no one. Not even themselves, because making decisions were a pain, especially with a murder loose on the ship.

"The usual, Will?" Black said, giving him a cheerful smile. Out of the five, Black has been the most energetic and cheerful one, even with a killer on the loose. "You know I don't like it when you call me that.." Yellow said, in a rather hissed tone. Black's been acting weird lately, at school, he's always the panic-ish guys i know.... what happened to him..? Yellow thought, thinking he was just paranoid. "Geez, sorry Yell..." Black trailed off, as he jogged to the cafeteria. "Time to do tasks for the billionth time today!" Yellow said, with a rather sarcastic tone. He realized as soon as there was no one at the hall but him, Pancake stopped growling. "Oh no,," Yellow said under his breath. if Pancake growled anywhere but the inside of the dorm, for Yellow, it meant danger. 

EMERGENCY MEETING!

"Ughhhh, did someone get massacred again?" Black said.
"Okay," Lime started off. "We- I mean I found Red dead in security." Lime said calmly, as if seeing dead people in space in the middle of nowhere was normal.
"Black." Yellow managed to blurt out, remembering Red pass by and Black follow not long after.
"Uhhh, pardon?" Black said, with wide, anxious eyes.
"Black, you followed Red. I saw you two pass by hallway." 
All five of them exchanged looks, while Orange, as the eldest left, planned whether to throw Black or not. Just then, they heard a sort of whispering scream coming from... Security?!?!

"Welp," Orange said "It's now or never." 

The quadro dashed into security to find Red, left arm amputated, right foot cut, laying on the floor. "Well, don't just stare idiots!" Red shouted, still screaming from the pain. Orange decided to carry Red While Yellow put bandages all over the patient, and Lime supported his nearly cut off foot. After getting him to medbay, bandaging him all over, Black gave him some medicine, and dozed off. "That almost gave me real heart attack." Yellow stated. Pancake was growling again, as Black sat next to Yellow. Red was sleeping-with his cat curling on top- Black was humming, Yellow was looking at Red, Orange was looking too, and Lime was the only one thinking who to throw. "Well it's definitely not Red.." But as he turned around, a look of horror was plastered on his face, with a bit of red something. Yellow happened to be holding a sharp looking knife.. Everybody looked... 

Black was dead. And on the floor, something was there. Something that looked very familiar to Yellow and Red. Something that looked like fur.
