On one peaceful day at Canterlot, everypony roams around the city for their shopping, walk to work, and other things they have to do. At Canterlot Castle, where Princesses Luna and Celestia lives, has royal duties to fulfill everyday and night.
But today they have an only day off for their break. Princess Luna's autistic Royal Guard, Golden Star, a kind-hearted crimson stallion, with a since of humor, was also there for the Princess of the Night; even if she's sad or stressed from other stuff. But today, he got his chance to make both Princesses bust out laughing like they never seen or what has done long time in their lives.
"Your highnesses," Golden begins to speak as he got Luna and Celestia's attention, "You two might know why I wanted to show you two that you haven't seen or heard before."
"Okay. Then what's you're going to show us, dear subject?" Princess Luna asks him.
Golden then walks towards the pillar of the throne chambers, and pulls out to be a type of a gas tank with wheels in front of them, as the Princesses got curious of what`s going on.
"Uhmm, Golden Star. What's that suppose to be in a that container?" Princess Celestia asked curiously, as Luna was thinking the same question.
Golden Star then nodded with a smile, "Well, Your highness, this is a tank filled with a type of gas called helium, a gas that are more denser than the air we breathe. But this one could kill you if you breath too much."
Luna then speak, "Are thou planning to kill us?!" Celestia was worried if he's planning to overthrow them.
But Golden Star then responded, "No. I would never kill you or anypony. But I wanted to show you something hilarious that you would like."
Still curious of Golden Star`s plan, he pulls out a balloon, and inserts it to the blower and pumps up the balloon. As the balloon`s filled with helium, Golden Star pulls the balloon holds to show his superiors.
"Now," he begins, "Here's what I'm going to do; I'll show you how I sound differently. I'll say in my normal voice like, 'hello' 'Good Morning' and 'how are you?' Now watch and learn."
"Okay?" Curious Princess Luna nodded, wondering what he's doing in front of her and Celestia.
Golden Star then inhales the balloon and starts to speak under influence of the gas.
He begins in a squeaky voice, "Okay, now I sound like this with this substance. I may say, 'Hello' 'Good Afternoon' 'Yes it's a stallion, What's wrong you?' Now you know why I sound like this."
Princesses' eyes were widened to hear something ridiculous for the first at first, until he finishes with the squeaky voice they begin to bust out laughing uncontrollably. They felt so interest in trying it too.
Princess Luna laughed, "OH MY TARTARUS! This is the funniest thing we saw! Hahahahaha!"
Celestia then stopped laughing and stated after wiping a tear from laughter, "Now that's the weirdest but funniest thing in our life, we've ever witness."
Both Princesses then claps their hooves and Golden Star pulls out two more balloons and hands them to the Princesses as they would give it a try.
They followed Golden Stars's instructions and now starts to say some ridiculous things.
"Salutations, dear sister!" Luna said to Celestia in a helium voice.
Celestia responded in squeaky voice, "Well, hello to you, dear sister. How're you doing?"
Luna then responded in helium voice, "OH nothing. Just talking while I'm inhaling helium."
Both Princesses laughs out loud, never thought of doing such funny thing like that.
"Oh glorious day!" Celestia said in helium voice, "I had a splendid day by talking with all of this malarkey with helium!"
Luna and Golden Star bust out laughing. Golden Star laughed as harder than the Princesses, until he accidently farted.
The Princesses looks at him, as Golden Star became embarrassed.
"Uhm...Excuse me." He said, still in helium voice.
But the Princesses started to busting out laughing, uncontrollably.
"You're excused, you little poop-headed turd!" Celestia nodded in helium voice. Golden Star and Luna starts to laugh hard.
When feeling that they're not alone, Golden Star turns and saw Princess Twilight Sparkle with Spike, wide eyed looking at them.
"Uhmm...Hi." Golden Star waved to Twilight, nervously.
"What the hay are you doing, Golden Star?" Twilight asked Golden, as he shows the instruction of how to speak in a funny squeaky voice.
After moments of teaching curious Spike and Princess Twilight Sparkle, they then joins in the fun.
Princesses Celestia and Luna, and Spike and Twilight, continues to clown around with Helium for a little time, laughing on say ridiculous and funny things.
"Oh my Equestria!" Said Twilight, under helium influences, "This is gotta be the most ridiculous, but hilarious thing ever to be test with science!"
"You got that right, Twilight!" Spike nodded with the squeaky voice. "Oh boy we're going to keep this all day, UNTIL ONE OF US FARTS!" Golden Star stated hilariously, as Twilight, Spike, and Princesses Luna and Celestia starts to laugh out.
As everypony was still laughing, Twilight Sparkle stood up with her two hind legs and said, "OH look at me, I'm Twilight Sparkle, and I'm still talking like a midget pony!"
Everypony stopped while looking at Twilight, until Golden Star then stated with helium voice, "Youre technically not a midget, but you Sound like one, unless you're a mouse!"
Spike and the Princesses starts to laugh of what Golden Star told Twilight, but Twilight frowned, and then responded with her squeaky voice, "OH LOOKING WHO'S TALKING! YOU'RE THE ONE TALKS LIKE A SQUIRREL!!"
"Ohhh! You'd just got burned, Golden Butt-Head!" Spike nodded under helium.
The Princesses, Spike, and Golden Star bust out laughing during this moment. Had a funniest time of doing some ridiculous thing ever they didn't do a long time.
While laughing at each other's voices under gas influence, Princess Cadence and Shining Armor walks in and stops with a wide eyes at the Princesses and Golden Star.
Golden Star, and Princesses Luna and Celestia then stops, looking at them.
Luna says to them, still in helium voice, "Uhmm, it's not what it looks like!"
