Peter snatched the spray can from Travis, "Fine, we can do a robot. But I get to do the paint.
Travis grinned, "Alright! It might not look the best, but we'll get points for creativity, right? Who does two-person costumes these days?
Peter started looking over the refrigerator box, giving it a base coat of metallic silver paint. "You better hope that no one shows up as a horse."
The two spent the better part of the hour turning a random assortment of junk into something resembling a boxy robot. Peter had focused on making a fancy-looking control panel on the refrigerator box's chest, while Travis built some boxy legs and feet that both of them could step into at the same time. The heads were a bit tricky, so they just settled on a pair of mop buckets with antenna pipe cleaners glued to the top. They had a large cutout in them so they could see, and a voice box drawn on the front.
As the party drew nearer, Travis climbed into the costume. He awkwardly got one of the buckets on his hand, turning in place slowly, "How does it look?"
Peter looked the outfit over, "I think it'll pass muster, but uh... We forgot the arms."
Travis looked down. Err, he took the bucket off his head, then looked down. He was covered in metal-colored boxes, save for the fleshy human arm poking out of the side. "Oh shoot, I knew I missed something! What are we going to do, we don't have time to build anything else."
Peter looked down at the paint can in his hand, "I think I've got an idea." He shook it up, and before Travis could protest, sprayed a shiny silver coat over the lower part of the pledge's arm. "There you go bro-bot."
Travis' eyes went wide, "What the hell man...!? Do we even know if this stuff washes off- Wait, Bro Bot was really good, you should write that down."
"Sure sure, hold still first though." Peter grinned, spray painting the rest of Travis' arm. He then sprayed the opposite arm on himself, before picking up a thinner paintbrush. With a flourish, he wrote, "Bro Bot 2.0" on the chest of the refrigerator box above the control panel. "Alright, make room, I'm getting in there."
Getting the two pledges in the costume was a trick in and of itself. Moving in sync was another thing entirely. Travis held his bucket-head in place. "No, left foot first, then right- Gah! Hold still!"
Eventually they managed to get into a good grove though. The two put their spare arm over each others shoulders, and started making more jerky-robotic movements that were more easily telegraphed to the other.
"Alright, here goes-" "-nothing?" Peter shot Travis a look, "Are you seriously going to try and finish all of my-" "-sentences tonight? Why not, sounds like a challenge-" "-to me?" Travis adjusted his bucket-head again. "Alright, point taken. Let's get going."
