Twilight is known for many things: being the shrunken student of Princess Celestia, an adventurer, powerful magic user, avid learner and reader, and more. But one thing she's never been is a prankster. When she learns about the holiday known as "April Foals Day" she decides to take part in the holiday and prank her closest friends and family for a few good laughs.

This story is a gift to my friend CommanderX5, the writer of Celestia's Tiny Student. Note that this is in canon with his story and takes place after Twilight's duel with Celestia, but before she meets the Wonderbolts.

One day, Twilight Sparkle discovers something amazing about her friend Sunset Shimmer.

She's a magical talking pony!

This requires investigation! Science! Possibly a full-body physical!

Or maybe Twilight will just ask her what's up with that.

Rated Teen for frank discussions about... y'know.

This story is a sequel to Sunset's Collection

Everyone has one, according to Rainbow Dash. Everyone has a collection of porn, even the quietest, meekest, and most mild-mannered. Rainbow is determined to find Fluttershy's.

Sex tag is for raunchy humor and porn jokes.

Now with a voiced reading!

Celestia has been waiting for this night her entire life; Twilight Sparkle has been destined to come for years upon decades upon centuries. But she didn't know to expect her student like this.

She steels herself anyway. She pours some tea, and welcomes Twilight with open hooves.

Then the two of them have a talk.

Spike, while browsing his selection of naughty magazines, accidentally coughs and breathes flames. The magazine gets sent to Princess Celestia. Panic ensues.

After transferring to Canterlot High, Twilight Sparkle realizes she has a crush on Sunset Shimmer. Being the analytical type, she develops a plan to capture Sunset's heart...using the scientific method.

Trying to patrol the dreams of every pony in Equestria can be stressful. To ease her burden, Luna retools the Tantabus to turn nightmares into good dreams instead of vice versa. Aware of her mistakes from last time, she tests it out thoroughly, making sure there are no unexpected behaviors. And as far as she can tell, there are none.

Except that it's started calling her "Mom".

Faced with the prospect of possibly creating life, Luna seeks out Twilight's advice and assistance. With a little luck, they can get this all sorted out before the sun rises.

It’s Fall Formal again, the last one they will have before they graduate. But even after almost three years and saving the world, Sunset’s still haunted by bad memories and pain that date brings to her... But this year, something changed. Because that certain girl’s there, and she doesn't has a pair yet. Maybe Sunset just needed someone to ease her pain. And that dork was there for her.

A lone vampire bat sneaks through the mirror portal and ends up in the human world. Instead of apples, it now craves something far richer. And unfortunately for Sunset Shimmer, she's its next snack.

Sunset can't remember any of her activities past sundown. The light hurts not just her eyes, but burns her skin. And she's thirsty.

So very thirsty.

It's up to the Rainbooms to save Sunset from herself before she drinks the whole city dry. Too bad Twilight Sparkle is her primary target.

Thanks to Saro0fd3monz for the inspiration!
