Prof. Propane looked up at the night sky, he wondered how the world moved, in fact, the Prof wondered a lot of things. Like how ponies came into existence, for example. Another is the fact at how the pony works, like how it walks and talks and thinks. But that’s just usual Prof. Propane, always wondering without a care in the world. He turned around back to his strange instruments on the table,
“Maybe if I mix this… yes, yes… and... yeah that’ll do.” He mumbled to himself.
He proceeded to mix the two elements in question, fun and joy, and there was an explosion! Not your normal ‘black smoke’ explosion. It was a rainbow explosion, with all the colors of the rainbow! The Prof had created liquid happiness! This was a great achievement among over ponies. The Prof poured the liquid happiness; you know, let’s call it Liquid H, into a small beaker, which he then put carefully into his bag.
“Time to show this to Ponyville!” He proclaimed, with joy, probably the effects of Liquid H.
The Prof trotted down the meadow, into the town, and set up a small stand. Being a unicorn, it was no sweat.
“Come one, come all! Come see what marvel I have created!” The Prof shouted over the heads of the ponies.
“Who on earth is that?” Twilight asked herself.
Twilight peered over the heads of the ponies to see Prof. Propane holding Liquid H above his horn with pride.
“Oh, it’s only the Professor!” Twilight replied to her own question. “What have you invented now Professor?”
“Hm? Oh Twilight!” The Prof replied, leaping down from his stand, “How divine to see you again! And in answer to your question, I have created liquid happiness! Or as I like to call it ‘Liquid H’! Pretty neat, huh?”
“Liquid happiness? What’s that?” Twilight inquired.
“It makes anyone around it happy!” Exclaimed the Prof.
“Really? Does it work?” Twilight asked.
“Course it does! Come, let’s go to your house and I’ll show you how it works!” The Prof exclaimed.
“Okay then Professor!” Replied Twilight.
While they were walking, they talked about the different things Twilight had learned throughout the years and what the Prof had invented. A few minutes had passed once they had reached the library. Twilight and the Prof took a seat and started discussing Liquid H.
“So, how did you create the substance?” Inquired Twilight.
“Well, I was just in my lab, mixing different elements, and then I came up with this! I call it, Liquid H!” The Prof exclaimed with pride.
“What did you use?” Twilight asked, as giddy as a school filly.
“Luna gave me some fun and… um … I think it was friendship… anyway, and I mixed them together to create Liquid H!” The Prof proclaimed.
At this moment in time you can probably now tell that the Prof had taken full effects of Liquid H, as he is not normally this gleeful. So Twilight thought,
“Better make the most of it.”
“Well, I better be off, I need to make an appearance at the local school, don’t want to be late! See you around!” The Prof said.
“Okay, bye professor!” Twilight replied.
Twilight soon followed suit and left, looking for Spike, she was sure he fell of at some point. But, they had left Liquid H behind, and when Liquid H is left unattended, bad stuff happens. Very soon, Liquid H turned slightly black.
Twilight had been out for 2 hours now, and still no sign of Spike.
“Spike! Oh Spike!!” Shouted Twilight, “Oh Spike, where have you got to?”
Twilight spent another few minutes looking for Spike, then, speak of the devil, Spike popped up behind her.
“Looking for me?” Asked Spike.
“Oh Spike, you have to stop hiding like this.” Twilight said, “I get really worried about you.”
“Okay, Twilight.” Spike looked at his feet.
“…And that, kids is why you never mix cola with a mento, any questions?” Asked the Prof.
The Prof looked at the small foals and fillies; their manes were all wet from the cola explosion.
“No? Okay then, I shall be off teacher, I believe I have left something at my dear students’ house, good day!” The Prof said.
"Haha, okay then, by Professor!" Exclaimed Miss Cheerilee,"Have a wonderful day!"
He trotted down to the library to find an eerie glow by the windows.
“Oh dear…” The Prof muttered, “Oh very dear, this is very, very bad!”
The Prof galloped into the library to find the floor filled with black smoke, he immediately galloped back out again.
“I must warn every-pony!” The Prof exclaimed.
The Prof ran into the town square and shouted,
“Every-pony! Run for your life! A terrible thing is about to happen! Possible including explosions, and really sweat action sequences! But in any case, run!”
All the foals and fillies and mares and stallions ran around trying to get out to the country side, screaming and hollering like there was no tomorrow, well there wouldn't be is the Prof didn't do anything. After about 10 minutes, Pinkie Pie, Twilight and Spike ran into the square.
“What’s happening? Is it a party?! I love Parties!!!” Pinkie Pie exclaimed.
“No, something far worse, it is just as I feared…” The Prof muttered.
“What is it, Professor?” Twilight asked.
“The Liquid H is starting to go sour, as you say. If it is not exterminated in the next 24 hours, all of Equestria will be doomed…” The Prof said darkly.
Pinkie Pies and Spikes jaws and hit the ground.
“What?! No Equestria?! That means… NO PARTIES!! WE MUST STOP THIS!!!” Pinkie Pie shouted.
“Good, now that you’ve got your, ehem, priorities right, we must act now!” The Prof exclaimed, “Come now, we must acquire the right tools to destroy it!”
“What has it become now, Professor?” Twilight asked.
“I believe it has now become… liquid spite…” The Prof replied grimly.
“But, why?” Twilight asked even further.
“Because, if happiness is left unused, it will become spiteful, jealous...”
“I suppose.” Twilight huffed.
“Now, let’s save Equestria, once again!” Pinkie Pie shouted, doing a back-flip.
