"Halloween!" C-3PO's robotic voice was filled with distain as he said aloud what time of the year it was. "Such an unpleasant event which humans really shouldn't indulge in! I don't see what's so celebratory about dressing up as hideous creatures of the undead in an attempt to get treats!"
As the golden droid stood in the centre of the dark room, having a hissy rant to himself, a small shape rolled up behind him. It was covered in a pure white sheet. It appeared to be illuminating as it made a spooky sound which filled the room.
"Whooooooo!"
3PO instantly turned around to face what had made the noise. He scoffed when he saw what it was. Not fooled that he was seeing a ghost in the slightest, his metallic hand whipped away the white sheet to reveal who was underneath it.
"You're not fooling me with that again, like you did last Halloween! Really, R2! Fancy a fully-built droid like you, taking part in this ridiculous nonsense!"
R2-D2 bleeped in protest upon hearing 3PO's remark, shining his lamp onto his fellow droid as its glow filled the dark room.
"Well I don't see what's so fun about dressing up as creepy things!" 3PO hissed. "And even if it was, you are not constructed to take part in fun, my dim little counterpart! You were out together for mechanical duties! Nothing more!"
R2 snorted indignantly at his stuck-up golden companion.
"No that's not true! The reason I hate Halloween isn't because I find it scary!" 3PO turned away from the small astromech. "I don't get scared in the slightest!"
A bleep of protest came out of R2 in response to 3PO's untrue claims.
"No I don't! Getting scared is simply not in my programming! Why would I be afraid of little younglings in costumes after all we have faced across the galaxy - none of which has frightened me in the slightest!"
"Bleep! Bleep! Bleep!"
"Why, yes, it may have seemed like I have been agitated in the times we have been caught up in intense space battles, persued by Inperial Stormtroopers and even under the ruthless ownership of Jabba the Hutt - but I can assure you I was not scared! I was merely, erm … putting on artificial fear in order to throw everyone off. As protocol droids are not built for conflict, seeing me acting brave would only cause our friends to worry. Of course, that's not something I would expect a deflect little nitwit like you to understand!"
R2 was not a bit convinced. He knew all too well how cowardly 3PO was. The golden protocol droid had done nothing but only panic and complain when the two of them had faced danger. It had been the little blue astromech who had shown all the bravery.
"And let's not forget I was in the presence of Darth Vader when Han Solo got frozen in carbonite - and I wasn't scared then!" 3PO added, neglecting to mention that was only because he had been in pieces and strapped to Chewbacca's back, unable to see Vader. "If he can't scare me, then nothing couldn't can!"
At that moment, a fierce hissed filled the room. 3PO turned around - to see that an enormous pumpkin was sitting in the middle of the room, eyeing him with a creepy sneer.
"Oh would you stop these silly tricks of yours, R2!" 3PO snapped. "You cannot scare me!"
Something tapped 3PO on his side. He turned away from the enormous pumpkin to see what it him.
R2 was standing next to him. He was lightly touching his golden companion with a mechanical arm. The small blue droid was shaking to and fro. His lamp was directly onto shining on the pumpkin as he peered past 3PO, letting off frantic bleeps.
"It isn't you?" 3PO exclaimed, his tone filling with panic as he turned back to the pumpkin. "Then … who is … what is … ARRRGGGHHH!"
A high-pitched scream of terror erupted from 3PO. He began to run around the room, absolutely petrified of the creepy-looking creature before him. R2 could only watched as he shrieked and overrated - as did the giant pumpkin.
"Help! Save me!" 3PO wailed. "Do something, R2! Call Master Luke! Call Princess Leia! Call anybody!"
It was at that moment when the dark room began to fill with bleeps once again - which sounded like they were not just coming from R2, but from another droid.
3PO stopped running and screaming. He glanced towards R2 to see that his counterpart was making a noise which sounded very much like snickering. It appeared to be coming from the monster inside the room too. He turned towards the pumpkin - before scoffing upon seeing that sliding into view on top of it, having lowered down where he couldn't see it, was a small, familiar-looking dome.
"BB-8!" 3PO cried. "Just what do you think you're doing?! Creeping about in the dark while painted like that!"
An small innocent bleep which sounded like a giggle came from BB-8. He tilted his dome forward to look down at his ball-shaped body - which had been painted up that evening to look like a pumpkin.
"Well of course I knew it was you in your Halloween costume all along!" 3PO claimed untruthfully. "Don't go thinking this trick you and R2 were both in on managed to frighten me! I wasn't a bit scared!"
R2 bleeped loudly. He knew his cowardly companion was lying. He had succeeded in him a good scare that Halloween. He whistled to the other droid who had helped him, resulting in BB-8 sticking out his lighter to give him a thumbs-up.
"Oh switch off!" 3PO huffed grumpily.
The end.
