"I can't believe they did that!" said Clary.

"My precious clothes" Izzy sobbed.

"I'm just glad that they didn't touch my glitter" Magnus added.

"Right that's it! We are getting some ducks!" Clary exclaimed.

"Erm… Why ducks?" Izzy asked confused.

"Well we need to bring out the big guns, and Jace's absolute hate is ducks, he's terrified of them." Clary said with a sly grin while slipping into one of Magnus' arm chairs.

"Umm Clary dear, Jace may be scared of ducks but how is that going to prank the rest of them?" Magnus asked looking confused.

"Well Maggie my dear by the time Jace is screaming like a little girl we aren't going to need anything else!"

The next day…

Jace was walking down one of the institute's cavernous corridors absent minded until he heard a curious sound.

"What the hell?" Jace said out loud, turning to open the door he had just passed that the sound came from.

"QUACK"

"F*****G hell, there's a BL***Y duck in here!" Jace shrieked "ALEC GET THE HELL IN HERE!" Jace turned as he heard a quack behind him "Ohh no please no, not behind me!" With his eyes closed he turned to face the noise, slowly he opened his left eye and stood frozen as he took in the sight of the corridor packed with ducks and within a second Jace was gone and all could be heard was a shrill scream as he pounded down the corridor.

Alec was sitting in his room shining one of his seraph blades until he heard screaming what the hell he thought while opening the door and stood awestruck as he watched Jace run past his room screaming. "Jace what's going on?" Alec shouted so he could be heard.

"Their behind me!" Jace cried and carried on running. Alec glanced down the corridor and was met with the sight of a stampede of ducks.

"Jesus Christ !" Alec shrieked "How the BL***Y hell did they get in here!" Alec took off running after Jace.

Alec didn't need to call for jace all he had to do was follow the screaming, soon Simon was running along side Alec "By the angel what's wrong with Jace?!"

"Apparently he's terrified of ducks!" Alec replied while coming to a stop in front of Jace's bedroom door "Jace you alright?" Alec called trying not to laugh. When no reply came Alec pushed the door open and strode inside. Jace wasn't in there. They turned to leave but stopped when they heard a sniffle coming from the bathroom.

Simon knocked on the bathroom door "You okay Jace?"

The bathroom door creaked open to reveal a shaking Jace "Are they gone?" He asked his voice barely above a whisper. Simon shook his head. "Alec call Magnus and tell him to stop this!"

"What we're giving up?"

"No just say if he stops this we will return all of there clothes!"

Magnus's apartment

The girls and Magnus were celebrating their win of a prank.

"YAY! IM GETTING MY CLOTHES BACK!" screamed Izzy.

Clary chortled "I wish I could have seen his face!"

"Ah but my dears the prank war is not over they might have something else in store for us" Magnus reminded them

At the institute

The boys looked at each other with sly grins "Their going down" said Jace.
