Disclaimer : I don't own it.

Note : This idea comes from hummergrey's fiction, 'If an Autobot, do NOT do the following'. This is following the basic 'prank' hummergrey mentioned, but with some modifcations specific for this chapter alone.

I am hurriedly posting the last of the chapters so that I can set this story as complete (though I do still have ideas put aside) and focus on another story I'm writing, for a while. This is the second last update.

Thank you again everyone, for being so amazing and taking the time to read and even review. Your comments are appreciated.

(Mikeala's POV)

"Do I even want to know how you got a hold of that image?" I felt my eyes widen as I looked at the mini form moving slowly and surprisingly....provokatively. Hm, maybe I can get her to teach me a few moves. Blinking, I shook my head and raised an eyebrow at the large blue eyes looking down at me. "You know what? Never mind. Let me look over the schematics again?"

The yellow 'Vette activated a holographic schematic of wiring, and I got back to work rewiring the bot in front of me. "Ok, I'm almost done. Just make sure to give me the words you want to act as key words."

"Oh man, this is gonna be great!" The silver 'Vette snickered evilly. "He's not gonna know what hit him."

I smirked. "Nope. Not one bit." Finishing up my work, I sighed happily, satisfied, and then began working on loading the different words and commands, and coordinating them with certain images that would pop up. Once I was done that, I snickered and closed up the panel under his right side and stood up, getting a lift from Sides, as Sunny replaced his arm by his side. "Test?"

Sides snickered and activated the program. Speaking several of the key words, he chuckled quietly when the corresponding images appeared, and then reattached some cords on the back of the mech's neck, before we beat a hasty retreat.

(The Next Day)

I walked down the hall, unable to keep from smirking as I spoke with Sarah and Maggie. I didn't tell them anything about the prank, but I think they knew. Then again, the constant smirk stuck to my face probably didn't help.

"Spill."

I shot Maggie a look and snickered a little, before shaking my head. "No, you'll see soon enough."

"Oh, come on." Sarah pouted a little.

"Nope."

"Please?"

"Nuh-uh." I shook my head again and giggled as we entered the rec room. Spotting Optimus Prime sitting on the couch, I felt a truly evil grin cross my features, before I masked my expression and walked over. "Hey boss bot. What's up?"

He looked at me and smiled a little, though looking slightly confused. "Not much, but I fear something is wrong with Jazz."

I blinked, and bit my lip as the urge to laugh came over me. I felt Sarah stiffen at my side, and turned to see her eyes wide and her jaw hanging limply, before turning as Maggie shivered at my side.

"Is something wrong?"

I shook my head. "No, I think it's just the, uh...spider....crawling......up your helmet." The two foot long, pink spider crawling up your helmet. I bit my lip as a giggle caught in my throat. Heh, key word 'fear'.

"I see."

Sarah made a rather suspicious choking sound, and Maggie flat out squeaked as a pair of giant glasses appeared over his optics. I faked a cough to cover my laughter, and placed a hand over my mouth. Key word 'see'.

"So how have you been today?" I swallowed heavily, sinking my teeth into my inner cheek to keep from laughing.

"I was rather tied up this morning, but I managed to get all the work done." A large golden coil of rope tied around his chest and wrists, although he was looking at us and never once noticed. "I am, however, expecting Secretary Keller later for a meeting." His entire form seemed to shift, putting a lot of emphasis on his lower abdomen, causing it to 'swell' so that he looked like he was pregnant.

Sarah lost it and turned, dashing out of the room in a fit of half muffled laughter, and Maggie snorted rather loudly, before giggling into her hands.

"I can see that." I muttered. Key words 'tied up' and 'expecting'. I began to wonder if he was going to manage to go through them all before the day was out. "And you wear the uh, expectancy rather well." I snickered a little as Maggie choked on her efforts not to laugh. "Oh, have you seen the femme commander?" I bit my lip, hoping he didn't lock on to the fact that I hadn't called her by name.

He tilted his head a little, but nodded. "Thank you." He was frowning, however. "Elita had a meeting of her own to go to. She'll be around later." He was still looking at us, so he didn't notice the tiny form of his mate, dancing provocatively on his forearm and shucking her armor as she went. Oh yeah, definitely gotta have her teach me some moves.

"Um, anyways. I need to go see if I can steal Sam away from Bee for a little while." I smiled toothily at him.

He nodded again, looking thoughtful. "It has been a while since they last visited, good luck with that."

I covered my mouth again, smothering the laughter that threatened to burst out when a large green hat appeared on his head, with a large four leaf clover hanging off the top of it. "Uh-hm." I faked another cough. "Thanks. I'll uh, see you later."

"Farewell." He nodded, before turning back to the television, the clover bobbling back and forth on top of his head.

With a choked laugh, I turned and dashed out of the room, Maggie hot on my heels the entire way. Oh, he was not going to be happy when he figured out what we'd done. Not one bit.

(Later, Normal POV)

"Optimus." John Keller nodded as he entered the rec room.

Looking down from his spot on the couch, Optimus offered the secretary a hand up, before turning fully to the human. "Ah, secretary. I've been expecting you."

The secretary's eyes got wide and his haw dropped. "I, uh... I...see that." He blinked a moment. Opening he mouth, he appeared he was going to say something, but he closed his mouth again after a moment, his lips trembling.

"Is everything alright?"

He nodded silently a moment, before clearing his throat. "How about you?"

"I believe the human turn is 'peachy'."

Keller lost it and began laughing when Optimus' entire body turned pinkish in color and became fuzzy. A large green 'stem' came out of the top of his head and the look was complete.

"Alright, now I know something is going on." A loud sigh was heard and Optimus shuttered his optics. "Everyone's been acting very strange today."

"Well, to be honest, I think you've been pranked." John snickered again and shook his head. "Whenever you say certain words, these...images appear around you. When you said 'peachy' you..." He snickered again and choked out a bit of a laugh. "You turned into a peach."

Blinking a moment, Optimus' eyes claimed a strange gleam. "I don't understand." A large yellow lightbulb appeared above his head, hovering in mid air as the secretary began laughing again. "I turned into a peach?"

"Key words, I suppose." Keller shrugged a little, biting his lip.

"Wonderful." Shuttering his optics again, Optimus shook his head. "I should have known. The twins are known for pulling the unexpected." He looked down at the sound of bicycle bells and frowned as a pair of identical blonde twins rode around the couch, blowing bubble gum, on one of those double seater bicycles. He blinked, before looking over at Keller. "This has been happening all day?" At his nod, he sighed.

"Busy busy, huh?"

"Very. They must have tampered with my holographic projectors while I was in recharge." Blinking again, his optics registered dozens of large fluffy feathers floating around his head. As he looked down, they appeared to fall, but as he looked up, they floated upwards. A quick experimentation showed they followed whatever direction he gazed in, before disappearing a moment later.

"This explains what everyone was laughing about." The sound of audience laughter filled the air around the room, and a bunch of red lipped mouths appeared, laughing around Optimus' head. "Yes, that would get tiring fast." Tires rolled by, and he growled slightly.

"Wrong tires." John murmured quietly, snickering into his hands.

"Very funny." Rolling his optics, Optimus slowly stood, offering a hand to the secretary. "Shall we go see if Ratchet is free?" Once the secretary was on his hand, he sighed. "I have to admit, they got me good." A frown covered his face. "I wonder what all the key words are?"

John began to laugh again, as a bunch of golden keys began appearing all over Optimus, seemingly hanging off his armor and jangling against his armor as he walked. "Well, I can tell you one."

At least Optimus finally had the answers to why everyone was acting so strange, and no one was seriously hurt. On the down side, he now had an excellent idea to get the twins back.

Hope you like it.

R+R please.

Thank you.
