Yeah, I know... 2 updates in one day! New rule, the more reviews I get, the quicker I upload, Lol :D :D
Thanks to SullyWullyBunny, The element girl, FrozenSakura20, mae2551 and MakinaCZ, who have faved/followed since the last chapter was up... Welcome guys, and *hugs* to everybody!
Just gonna jump right in here... Let the Pranks begin! (Oh, and this is set straight after the last one, for anyone who's confused :D )

Sandy grinned as Jack explained his ideas and how to carry them out. It appeared he had had these plans for some time, but had needed a partner.
Frankly, Sandy was honoured. The only one who could beat Jack's penchant for pranks was old April Fool, and to have Jack actually helping him get his revenge? This was going to be great!
Especially as he had a very specific prank-that the others had played on him-to make up for...
He had to admit, the detail that went into the plans was genius. Jack had even anticipated the actions of the three other guardians, and used them against them...
Sandy realised that he really should not ever let Jack meet April Fool... It would mean the end of the world as they knew it...
With a grin, he high fived Jack, and they both head off to make preparations.
For the first time in quite some time, the old guardian felt ridiculously young...
_

North stared at the two other guardians, one gold and one white, and frowned from behind his Yeti shield.
"Sandy... Jack... What brings you to Pole?"
"Just dropping by..."
Sandy signed something, and Jack grinned.
"Sandy says remember April Fools of 1935?"
North went pale, and held up his hands.
"Now Sandy, I'm sure we can be reasonable about this... I'll get Bunny and Tooth and we can discuss this like-"
Sandy signed something again, and Jack grinned an identical evil smile.
"Sandy says he promised vengeance... Yeah, I thought vengeance sounded cooler and more terrifying that payback-" Sandy nodded, approvingly, before Jack began again. "Sandy says he promised vengeance, and the next few weeks will make his revenge a reality... So, as a little welcome to the crusade gift... Elves! Go!"
Fifty elves opened the lids from bottles, throwing them down, and dove behind an ice wall that Jack threw up, surrounding North and the Yeti's, which fast morphed to a dome.
Everything inside exploded.
A few minutes later, and with North and his chosen army completely covered in foam, the two guardians threw down their flag, covered with their new symbol –a snowflake, inside a dream bubble with a punk styled Mohican... Pretty cool Jack thought- before taking to the skies, North's curses and threats of the naughty list echoing behind them.
Mentos and coke... Classic...
Jack and Sandy high fived on their way to 'visit' Tooth and formally bring her into this prank war.

Tooth, wearing full Fairy battle armour, including a helmet, gave the two a suspicious look from the other side of her invisible bubble shield.
"Jack... Sandy... How are you guys?"
"We're good... Just had a very nice visit with North. Discovered he didn't like Mentos and Coke..."
Tooth shivered, both from the horror of the mental sight of the foam explosion she knew had occurred, and from the amount of sugar in both coke and mentos, and was glad she had put up the invisible wall between them.
"Ah. Sounds... Fun."
"It was..."
Sandy began to sign, and Jack grinned.
"Sandy here says he has a message for you... He says, remember the Prank of 1935?"
Tooth froze, face going pale, and Jack grinned.
"Funny... North acted the same way... Anyway, Sandy says it is time for payback... What? I figured it would work better than the word vengeance this time..." Sandy rolled his eyes, giving a reluctant agreement, and Jack grinned.
"Right... Anyway, where was I? Oh right. Time for payback... On three... One... Two..."
Tooth was literally close to biting her nails now, and was wondering whether it had been a good idea to trust the few dozen fairies she had chosen... Ah well too late now...
"Three!"
With a swirl, a gust of wind-he had the wind on his side? Tooth nearly cursed- swirled into the room and spun in a tornado. Jack threw a load of pink powder into the air, and Sandy formed a sand wall around the spinning horror.
Then Tooth realised what it was, and gasped.
No... They wouldn't... They hadn't... But they had.
It was a giant... Candy Floss Maker!
The make-shift monstrocity eventually exploded, littering the entire room, and many of the corridors beyond it, with pink fluff. Made entirely of sugar...
The two high fived, before flying out, leaving Tooth to threaten them with... wait, was she threatening to floss them for the rest of eternity?
Sandy grinned. This was better than anything he could have come up with himself...
But the first prank they were going to play on Bunny? Oh, this was going to be fantastic...

Bunny, having been warned of the horror's that his friends had succumbed to, decided to just get the guardians of the warren to block the entrances...
What he didn't realise was that Jack had been prepared for this eventuality for quite some time, and had dug his own tunnel that went from beyond the curve of one of the tunnels up through next to the rivers of dye.
Sandy had been amused by the obvious preparation that the kid would put into his pranks, and was sure they should be considered an art form.
They quietly drifted through the tunnel, and peeked over the ridge, to see egg patrols, each of the small things armed with what looked to be mini dye spray guns, and Bunny himself stood on patrol.
This was going to be tough... Or maybe not.
"Okay Sandy, ready?"
He nodded, and Jack grinned, just as Bunny caught sight of them.
"Okay, NOW!"
Before Bunnymund could do more than blink, he had been hit with a ball of dream sand. The eggs were likewise coated with the stuff, and Jack grinned as he motioned for his own forces, namely the elves he had managed to recruit into his service for the payment of him not pranking them for half a decade, to get out the eggs he had prepared for this.
Each blue egg, a snowflake pattern covering it, took the place of the-now sleeping- eggs, which Sandy moved to a safe place, the other side of the northern half of the warren. Then Sandy went about hanging up a variety of Christmas lights, sneakily borrowed from North's old workshop rooms, and various other Christmas decoration around the whole area of the warren, as Jack turned it into a winter wonderland.
It was only a semi-permanent thing, as he didn't want to damage the land, and it would clear within a few hours, but it would likely push Bunny to the brink of irritation. Just to the brink... They didn't want to leave his nerves in tatters on their first run now, did they?
Within half an hour, the place looked like the very epitome of Christmas, and, as he had done with the other guardians, Sandy was quick to take a lot of photos, which they were planning on making into a book.
For a Christmas present for the other three.
Then, Sandy left a message in the snow, which read
For the Prank of 1935... Beware E. Aster Bunnymund. This is only the beginning...
Then Jack couldn't help adding,
It's like Christmas has come early- Oh wait...
They only waited around to see Bunny wake up, in order to snap a few pictures of the horrified expression, and the gulp and scowl as he read the messages, before they high fived and used one of North's globes to get out, leaving Bunny to wonder how they got in, seeing as he locked his Warren from that kind of entry...
_

An hour later, they were at their base of operations, a small, multi-roomed Ice Castle that Jack had built for this sole purpose, Sandy having no problem with the cold and the elves being used to it, and were hovering around the huge round table they had all their plans laid out on.
Now there was just one more person to prank before they called it a day, and settled down before planning to use the next day to prepare the next bout of pranks...
Sandy grinned as they finished the preparations for the final prank, and they both ran from the place, splitting up as Sandy went to do his job and Jack head back to finalise the next plans.
No-one cold figure why the children's dreams were all full of pranks and such over the next few weeks...

A few hours later, North, Bunny and Tooth, who were all sat in the study making a battle plan, were astounded to see Pitch storm in.
"Does anyone want to tell me why I returned to my place to find that the entire area had been lit up with... FLOODLIGHTS? Hmm? Anyone? It looked like the middle of summer in there!"
It didn't take long to explain, and the Nightmare King scowled as he swept back out again, reassured that he would be left in peace... The other guardians knew that there would be no more pranks on Pitch, but still... Man, those two had guts.
They hid their laughter as they continued with their plan- trying to ignore the sugar high fairies who seemed to have decided that by clean up, Tooth had mean eat the candy floss- deciding it would be best to stick together, and move from place to place... Not realising that, by doing this, they were doing just what the other two guardians wanted...

Yeah, definitely going to be taking up another chapter or two... The next chapter will have lot more pranks played on the three of them, and Jack might even drag an old friend or two into it...
But what did you think of the pranks? Evil enough?
