I like him when he isn’t being goofy.

@Kirb  
I like his goofier stuff, mainly for the kitsch value.

When she’s not on wheels, Scootaloo can use her wings to create powerful gusts of wind.

Moondancer and Starlight Glimmer do not get along with each other at all. Moondancer is very protective of her best friend and doesn’t trust Starlight Glimmer in the slightest; likewise, Starlight Glimmer sees Moondancer as a threat to her relationship with Twilight Sparkle. Twilight just wishes the two of them would learn to get along.

@Crystal Neighybánya
 
When Sunset comes by for her weeklong visit every year, she, Trixie, Moondancer and Starlight show off their magic for Twilight.
 
They have also formed a sort of think tank/study group, digging deeper into the magical sciences than anypony ever has before.
 

@Scrounge  
Scootaloo will eventually achieve flight through a glider powered by the thrust from her wings.

@CobaltTheMadMage
 
Just like her idol Rainbow Dash broke the airspeed record, Scootaloo later broke the endurance record for longest uninterrupted flight using her glider.

@CobaltTheMadMage  
Maybe Scootaloo’s days of flightlessness really will get resolved one way or the other next season. That’s the elephant in the room for the CMC now they’ve got their cutie marks.

Twilight loves that she gets books every year for Hearth’s Warming, but would love it if she could get a new pair of socks for once.

@PonyPon  
you know, when later on in life, when all your socks seem to keep getting holes in them, you start to wish you get sock for Christmas

@ice1517
 
Funny how that happens.
 
As a kid, you wanted to stay up all night, but your parents made you go to bed at a reasonable hour.
 
As an adult, you’re perfectly happy to go to bed at a reasonable hour…because you have to get up early tomorrow morning.
 
As a kid, you hated getting socks for Christmas.
 
As an adult, you’d think getting socks would be pretty great, since that means you don’t have to buy them for yourself.
 
As a kid, you hated eating broccoli.
 
As an adult…you still hate eating broccoli.
 
I guess some things never change.

@YetAnotherBrony  
Hey! I like broccoli. :P

Mirror Pool is sentient being. It can decently copy personality of one person, but gets dizzy when trying to copy entire crowd (i.e. more clones -> personalities become more and more ‘flat’). Spell just returns it to it’s home without any harm.

@Background Pony #EB68
 
I like this idea.

Anthro!Derpy doesn’t like wearing shirts. She can handle jackets, though, for some reason.
 
@Magma_ERuptiOn  
We haven’t seen her flap or fold them since FTTF.

@ice1517  
Socks are nice, especially if they’re cashmere socks.

@Crystal Neighybánya  
I was actually thinking less creepy and more just pathetic, but I like your version better. :)
 
That said, Twilight doesn’t think of Starlight when she hears “yandere”. The first pony to spring to her mind is actually Fluttershy.
 
@YetAnotherBrony  
Scootaloo currently holds the land speed record for a pegasus. Do not mention this while she’s within earshot.
 
@PonyPon  
Twilight puts a lot of effort into making sure the books she keeps giving Spike as gifts are ones that he’s got a reasonable chance of enjoying. Not that it matters, because once Spike sees that it’s yet another book, he doesn’t even look at the cover any more.
 
@Crystal Neighybánya  
Sunset Shimmer, on those occasions she visits, has threatened more than once to lock the two of them in a tool shed together until they either learn to get along or kill each other. She also locked Trixie in a tool shed without warning, but apologized shortly after letting her out, as it was human Trixie she was really mad at and taking out that anger on pony Trixie was actually kind of embarrassing in retrospect.

@Scrounge  
Heh. Thanks.

Oh, one other thing:
 
<”HE DIDN’T GET OUT OF THE COCK-A-DOODIE CAR!!!”)

Scootaloo can’t stand Zipporwhill. Zipporwhill constantly darting and zig-zagging through the air like a parasprite on a sugar rush just makes Scootaloo resent her for even showing up.

The Royal Guard and Wonderbolts are actually quite competent and formidable.
 
It’s just Equestria is such a “death world” that even years of training can still leave someone unprepared for Equestrian monsters.

here’s one in amending fences twilight did bring pinkie back but not lyra because twilight hates lyra, now lyra didn’t do anything to make twilight upset

Scootaloo has numerous problems with her reproductive, urinary, respiratory and digestive tracts, namely, some embryonic ducts not fusing properly. She was born with various epiglottal defects, which is problematic not just for biological reasons but causes problems in speaking as the Equestria language frequently features /ʡ/. Similarly, her (ndegesebaceous) gland, though functional, was underdeveloped. She was also born without a uvula. Most of her digestive tract is fine, however, the division between her jejunum and ileum was closed by a wall (I believe the difference is internal width and lymph node distribution) and the two instead merged at the jejunal atrium of the ividzukofirorocśaifnƥrek. She has uterus didelphys, and her urinary syster has similar problems. Both urethral sphincters were nonfunctional and only one kidney worked. Surgery was able to correct this, however, she was tube fed until she was three, padded until she was six and wet the bed until she was twelve. The problem with her flight is believed to be a similar duct fusing issue, though how pegasus flight works is at this point a complete mystery.
 
When she met Apple Bloom and Sweetie Belle she was just out of hospital following the latest bit of surgery.

@Wiimeiser
 
You’re building a world right down to a character’s individual internal organs, it seems.

@YetAnotherBrony  
Yeah, a lot of the “destiny bearers” have problems (I made some changes to Scootaloo above just now), for example, Apple Bloom has Marfan Syndrome, Sweetie Belle has Lexical-Gustatory Synesthesia and a cybernetic arm, and Flandre is an albino.
