Shining Armor sighed a breath of relief. If he arrived even a second later, Blueblood and Cobalt would be on the floor wringing each other's necks... wait, scratch that, actually it would be more like Blueblood wringing Cobalt's neck, who would be giggling like a maniac.

"Pushing Blueblood's buttons is not going work, Cobalt," said Shining, as he sat down.

"Thank you, Shining,” huffed Blueblood as he calmed himself down. His charlatan tricks almost worked though."

"I was not joking my son, would your future father ever lie?, " said Cobalt with a modest grin.

"Cobalt, I'm gonna kill you! You bungler!," said Blueblood as he lunged towards Cobalt.

Fortunately, Shining snatched Blueblood in his magic.

"Ahh, I see what Cobalt was up to," chuckled Shining as he levitated Blueblood back to his seat, whose hooves were crossed.

"Okay, let us get this over with," Shining said, his tone becoming serious.

Blueblood responded in agreement." Yes, enough fooling around."

The two unicorns stared at Cobalt, waiting for a response.

Cobalt stared backed with equal intensity but eventually relented.

"Fine!, I will cooperate," said Cobalt, raising his hoof in defeat

Two heads are better than one after all...

5 minutes later

"Okay," said Blueblood, slowly."So you promise you are not going to do pranks today?"

"I Pinkie promise!, Cross my heart and hope to fly, stick a cupcake in my eye !"

Cobalt promptly took the cupcake from Shining's hoof(the cupcake Cadence made for him) and squashed it into his eye.

Blueblood winced at the grisly sight." I'm going to be sick".

Unlike Blueblood who was now officially scarred for life, Shining was more concerned about something else

"Awwww, I was going to eat that!," whined Shining."Cadence made that just for me!"

"Here, have a strawberry cupcake," said Cobalt as he miraculously retrieved the confectionery from his hair.

Shining took the cupcake.

"My good pony are you going to eat a cupcake that came from a ponies mane? I mean how did it get there in the first place!," questioned Blueblood."Now put the cupcake down.. ".

NOM NOM NOM.....

"Argg!," groaned Blueblood, his head on the table." I do not know why I even try."

"itsds deligfhuous!," said Shining with his mouth full causing Cobalt to chuckle.

"Yeah!, my little cousin Pinkie baked it, and she's still a foal!"

Blueblood picked up his head." I did not know you had a cousin."

"Me neither," added Shining.

"I only found out that she was my cousin three years ago, they live on a rock farm, which explains why it took so long to find them."

"That is remote as you can get," said Shining, nodding in agreement.

"This Pinkie seems to have a great influence over you," said Blueblood.

"Yes, she taught me everything I know! and it all started on that fateful day, three years ago..."

Shining groaned silently."O no, his reminiscing his past again'', whispered Shining.

Blueblood sighed. There was nothing he could do.

Blueblood and shining were lucky that they woke up just in time at the end of Cobalt's Tale.

"...All of a sudden she was bright pink and her hair was poofy. she was not the only one to change though...anyway, in conclusion, that day gave me a lot of things including my earing."

Cobalt pointed at his right ear presenting a stud with a pink crystal on it.

The unicorns nodded their head.

"An enthralling tale Cobalt", commented Blueblood.

"Interesting life experience," said shining, stomping his front hooves.

Cobalt smirked."you do know that I was aware that you two were not listening."

"What an absurd accusation!," exclaimed Blueblood." We did no such act."

"Yeah! We were not sleeping at all," said Shining Armor.

oops...

Blueblood faced hoofed."Shining you blithering fool!"

"Nah, it's fine," said Cobalt, waving a hoof and waking up from his chair." I will tell again next time and do not worry, I am not going to prank anypony today. I pinkie promised and you never break a pinkie promise."

After saying what he had to say, Cobalt left the cafeteria.

Blueblood felt a sense of uneasiness as he and shining walked towards their last lesson, Chemistry. Cobalt was going to do something but if not a prank what else?

"You look tense," noted shining.

"Are you not too?"

"Nope, Cobalt 'Pinkie' promised. I have never seen him more serious than that.Ever."

"Then why I have the feeling we going end up in my mothe- I mean my aunt's office again?"

Shining sighed."We going to just wait and see."

_____________________________________________________________________________

The chemistry lesson went surprisingly well. Even Sir Redox, the chemistry teacher, was suspicious. He kept on glancing at Cobalt every minute but relented. He, of course, was not the only one, Blueblood also kept an eye on him but he would receive a cheeky grin from Cobalt.

"Just let it go Blueblood," said Shining Armor tapping his shoulder."Cobalt is not going to do anything. Three-quarter of the lesson is already over."

Blueblood relaxed. Shining was right. Everything is going to be absolutely...

"And as you see students when I pour this chemical to..."

BOOM!!!!!!!

PRINCESS CELESTIAS OFFICE

The three stallions stood in a straight row in front of the princess with the Professor by the side, fuming with rage. He was covered with confetti excluding his mane which was singed at the ends and His beard, which was still smoking.

"It was them, your highness! The ringleader and his two accomplices!"

Blueblood sighed. They always get involved with Cobalt without even getting involved in his plans. His mother like aunt gave him a disapproving look. The type of look that comes before a very very long lecture.

"Do you have any proof Professor?" questioned the princess, her face expressionless.

"Your majesty, yes I do!," said Sir Redox, triumphantly, looking at the three stallions, especially at Cobalt." This time you all are done for!"

Sir Redox placed the videotape in the record player." This is all the evidence you to expel these ruffians, your majesty," said The professor as he fumbled with the device. " Well, not the prince of course. He just fell into bad company of that middle-class unicorn and that commoner."

Blueblood scowled at the professor. that no good noble suck up. He looked up and sure enough, the princess was also giving an annoyed look at the professor but he was too busy getting the video ready to notice. Blueblood looked at him to com-padres. They did not seem to have heard what the professor said. Cobalt was whispering something in Shining's ear, who was grinning. Blueblood buried his face in his hooves. Even on the possibility of getting expelled, they still act like little colts.

"Aha!," exclaimed the professor as he successfully started the video on the TV." Here is your evidence!"

Everyone, except for Cobalt, was staring at the screen. Expecting footage of Cobalt doing something to link him to the confetti bomb but instead, they received one Chemistry Professor singing in the shower.

"My eyes, they burn!," exclaimed Blueblood, as he immediately covered them.

Cobalt and Shining were laughing to an extent they rolling on the floor. Even the princess was trying to keep a straight face.

"What!", said Redox, his cheeks turning red with embarrassment. He quickly snatched the videotape from the player.

"Learners wait outside", ordered the princess." I will decide your punishment later for embarrassing Sir Redox"

"Yes, thank you princess ...wait what about the Confetti bomb?".

"I am afraid you do not have any proof Redox", said Princess Celestia.

"No!," said the Professor I got more evidence!here!see these are the materials found in his school bag that he could have used to make the confetti bomb'

The princess levitated the two objects. her expression showing confusion."A toothbrush and a screwdriver?"

"Princess this is Cobalt we talking about! Laws of logic do not apply to him! I mean are you not suspicious at least? Who carries a screwdriver to school!"

"That is enough Redox," said Princess with finality in her tone."You do not have any substantial evidence so I suggest you leave it be.

Redox kept quiet. He heard the warning well and clear."Very well your Majesty," he said, bowing.

"Now what was the other reason you came to see me for," said the princess as she repositions herself on her seat.

Redox's mood immediately lightens up.

"Ahh yes...," said Redox, mentally smirking. If he can not expel that filthy commoner. Then this is the next best thing, after all this does belong to him.

"I made a huge discovery your Majesty," said Redox as he levitated a small box from his saddlebag." An object that contains the same if not more energy than alicorn magic...your magic.

Celestia looked at him with surprise. Could it be?.No, she hid the elements of harmony safely but if not the elements what could it be?

she watched as he slowly opened the box revealing

"Bird food?"

Redox looked bewildered. It cannot be! How could he have possibly stolen it back? Redox looked at Celestia who was radiating pure energy.

"Do you think this is funny Professor," said the princess her voice dangerously low.

"Oh no", thought Redox this is going to be a long day...

ROYAL GUARD REGISTRATION OFFICE

"Ow!," said Cobalt as he rubbed his hoof."Do you have to hit that hard?"

"Yes I do," said Blueblood angrily." You almost got us expelled! On the last day of high school no less! All for that stupid bracelet"

"But we did not get expelled."

Blueblood calmed down."I guess you are right".

"So what punishment your mother is giving us"

"Shhh! you dolt! Do not say that. We in a public place!"

Before Cobalt could reply a blur of white and blue squashed them in a huge hug.

"I have been recruited into the royal guards!," exclaimed Shining.

"I'm so proud of you. I knew you would make it," said Cobalt".

"Indeed we are but we first have our punishment to do if we want to celebrate at donut joes place."

What is the punishment?", asked Shining.

"Washing and drying dishes..."

"That's not too bad," said Cobalt

"Hmmm. Let me rephrase that. Washing and drying the palaces cups plates and glasses that number in total 12098, to be exact."

Cobalt and Shining groaned.

"Now, now groaning won't get the dishes clean. Let us go and get it over with."

Far away in a small rock farm...

Little Pinkie clutched her chest.

"Cobalt what have you done?"
