A/N: This one goes out to Ally Marton! Thanks for the idea!
Most days, the Young Justice team found themselves busy with one of two things; School work or crime fighting. However, they always had some amount of downtime, when they had nothing to do at all. It was on days like this that the kids were usually in the most danger, mainly because they often enjoyed finding dangerous and often gutsy things to pass the time with. Today was one of those days, as proven as Wally ran around the cave at his top speed, shutting all the windows and doors he could find. He was so wrapped up in his work that he didn't notice Dick as he entered into the main room of the cave and began to look around curiously.
"Hey Walls, whatcha doing?" The little bird asked, stuffing his hands in his pocket and leaning back on the balls of his heels.
The speedster ignored his friend, and instead he raised his hand above his head quickly and suddenly. In the red-head's clenched fist there was an item that Robin could just barely make-out. It was a small blueish silver sphere...A bouncy ball!
"NO WALLY DON'T!" Robin cried as he hit the floor and curled up into himself, waiting in horror for his friend to put the ball down or throw it.
But it was to late and Wally threw the ball hard against the wall. It raced around the room, knocking objects off the shelves and nearly hitting the two heroes, who by then were on the floor covering their heads, at full force. This went on for a grueling seven minutes but then it just stopped with a muffled 'Thud'. Suddenly a loud 'OOF!' was heard, and the boys looked up quickly and gasp in their surprise at what they saw. There, laying on the floor with his limbs sprawled out, they saw Simon laying on the ground next to a randomly placed open window. The mind-controlling villain seemed dazed and looked very confused and almost scared as he sat up and looked around the room, his eyes landing on the two heroes, who had taken his moment of collection to get their weapons ready for a fight.
"O-Oh dear..." Simon muttered, covering his head quickly, clearly in no shape to fight back.
"Hey, Walls, you take the left and I'll take the right!"
By the time the League showed up and got him to come to (Simon having been knocked back out by Wally and Robin), he looked up at them in the same shock and fear as before, simply babbling random things until Black Canary slapped him across the face to knock some sense into him. He shook his head quickly and then struggled to his feet, his arms held behind his back by Batman as he turned to the two younger heroes and asked.
"What kind of weapon was that!" He asked as he sounded almost amazed.
"Weapon?" The whole league asked in unison, their eyes darting to the two boys in surprise.
"The blue thing! It hit me in the head and it disrupted my brain blast!" He explained, looking around for it on the ground.
Wally smirked suddenly, and once again at his top speed, he raced to just a few yards outside of the cave and reclaimed the toy that he had lost earlier, and then slid it into his pocket, leaving every adult in the cave in amazement. At this, the league now had bouncy balls labeled under use-able weapons.
