Contrary to popular belief, the chibis could communicate with each other without the use of flashcards. Maybe it was a secret subroutine Donny forgot to mention, maybe it was solidarity of being mute and tiny. Whatever the reason, all a chibi needed was a look, a gesture, a smile to understand the thoughts of the other.

And that was exactly the way the Plan was born. A wide grin, and an emergency meeting was called during a visit from the human-chibis. Soon, through a way no one would fully understand, an entire discussion took place, the weighing of pros and cons included. Soon, their individual duties towards the Plan were divided equally between all eight chibis.

Thus, they went to work.

"Chibi-Me? Chibi-April?"

A pause in tiny footsteps.

"May I ask why you're taking the thread and needles?"

The two chibis shook their head furiously.

"Well, alright. Just be careful with those."

A nod, and they were off.

"Hey, Chibi-Us! How's it goin'?"

A little emerald hand held up a sign.

"What's that?"

Raph rolled his eyes, and took the tiny sign. From his belt he removed a magnifying glass, and took a moment to find the right distance from the written-on surface so that he could read it.

He blinked, and looked back at the two chibis. "You want to tape us saying what?"

Three small hands pointed at the sign.

Mikey took the magnifying glass, and checked. "Seriously?"

Three pairs of eyes shone pleadingly.

"Fine. I'll just find a tape recorder."

Chibi-Rafieo held it up helpfully.

Leonardo stared in confusion. Chibi-Him was sitting in the middle of their shared room, painstakingly laying a long piece of thread on a ruler, and marking where each inch ended.

After a few moments of watching the careful activity, he shook his head, and went to the dojo.

He didn't really need to know.

"Chibi-Me? Why are you cutting up my clothes?"

Chibi-Casey looked up guiltily from the dress shirt that was about to become a vest. An already mangled sweater and jeans lay near him.

"Well?"

A little black head lowered in shame.

"Aw, Hell." A pause. "Look, just leave that shirt, 'kay? I'll find you some clothes to make origami from."

A grateful smile.

Chibi-Shredder dutifully dug through the pile of discarded objects, fishing for eight containers small enough for them to hold in their hands. When one was found, it was handed over to Chibi-Splinter, who washed/cleaned it till it sparkled.

Lastly, it was deposited on the steadily growing pile.

Finally, the last stage was ready to commence.

The eight chibis gathered in an empty room, and readied their supplies – a bunch of small containers, pieces of different cloth, thread and needles, scissors, paints & crayons, and a measuring thread. Carefully, they measured their limbs, Chibi-Donny writing down each number on a piece of paper they pilfered from Master Splinter. Another piece was used to draw out the rooms of the Lair and their future route through them.

A few hours later, they were ready. Just in time too.

It was late enough that all members of the Clan + two human guests were locked away in their respective rooms. All the better for the chibis – they marched over to the first stop on their route without distractions or interruptions.

Chibi-Rafieo slammed his fist against the door several times, the sound of which carried through the Lair like semi-loud knocks.

After a few moments, the door opened, and the terrapin standing in the doorway stared at the small group of dressed up chibis.

Chibi-Rafieo lifted the tape recorder, and Chibi-Mikey pressed the play button. All the chibis grinned, lifting up their pumpkin-painted containers expectantly, while the recorded message sounded.

"Trick or treat!"
