I have no idea how to write a fic based on a show that relies on dialogue and visual effects, so here's something like a script. Also might be related to my comic.

"What? Who replaced my hydraulic fluid with bacon grease? GRIF!"
"What? I needed a place to empty my grill."
"Why would you store your disgusting pig fat in a can labeled 'Simmons Replacement Hydraulic Oil, Do Not Empty'"
"And it's not empty! See? I did you a favour. You owe me. Now if you'll excuse me, it's the first day of the month, and my break time just got refilled."
"You take a break for the whole month anyway! Wait, it's April. Ohhhhh, I get it now."
"How the hell do you know it's April? The sun never sets around here. Also, why the hell does no one care about that?"
"It's April 1st! Ha! You were just playing a prank on me! Don't worry Grif. I'm not mad. I'll just be right back."
"Hey, don't ignore me! Wait, where are you going? Ah screw it, I think I'll just take a nap."
-o-
"Grif! It's nice to see you. You look very... yellow today."
"For the last time, Caboose, I'm orange. What are you even doing here anyway?"
"Oh, Simmons wanted me to give you a message!"
"Okay..."
"..."
"..."
"..."
"Well, are you going to give me the message?"
"Oh, right. Simmons said that he is in charge now that Red Sergeant has been gone for a while. He also said some things I didn't really understand, like how everybody will look up to him now- wait. I know! Simmons grew taller, he must be going through puberty!"
"Caboose. Shut the hell up and get to the point."
"Right! Simmons wants you to go and move some boxes around in the storage building."
"He expects me to do heavy lifting? No way."
"He also said that I should help you out! He promised me we would get cookies when we finish!"
"Wait, you're really strong. Maybe I could just sit back until the job's done, then get free cookies! I'm a genius! C'mon Caboose, let's get those cookies- I mean boxes."
"Okey dokey. Let's go, Freckles."
-o-
"Uh, Caboose?"
"What is it, Grif?"
"There's only one box here."
"That's great! Why don't you move it so we can get our cookies?"
"Ah what the hell. It's just one box. What's this? There's a note. It says, You want a prank war? I'll give you a prank war. Wait what?"
"I almost forgot! Simmons told me to help you move the box."
Confetti shoots out all over the place.
"...Did you just try to shoot me?"
"No silly, I was just helping you move the box! Oh, I've got a great idea. Freckles, help out Grif too!"
"Look, I don't know how it works on Blue Team, but we don't-"
"Affirmative, Captain Caboose."
"Did your gun just- SON OF A BITCH!"
"…."
"…."
"...not my fault."
