Because I can.

First Row: Tic-Tac-Toe tells Baby Tic-Tac-Toe a story…

Yes, that story is the canon explanation for the Twinkle Eye Ponies’ eyes. It appeared in Issue 11 of a My Little Pony magazine released in the UK.

Out of the eight Twinkle Eye ponies released, only two of them eventually got babies. These were Baby Quackers and Baby Tic-Tac-Toe, and they didn’t have the gem-like eyes that their moms did. At first, this seems a little odd, but when you combine their non-twinkly eyes with this story, it actually makes a surprising amount of sense!

Second Row (left): Poor Twirler — nothing like having an outmoded media format as a symbol to make you feel ancient. (The baby pony is no one in particular. Also, in case the joke goes over any younger viewers’ heads, those aren’t CDs.)

Second Row (right): The second G1 Twilight (e.g., the Twilight that hardly anyone talks about) is way out of the loop.

Third Row: The unfortunate story of how Baby Fifi came to be (one fan’s interpretation).

The setup to this comic is based on another story from the UK MLP magazine (Issue 1), and it actually does make a strange amount of sense — in a land with no male ponies in it (at the time), where were all those baby ponies that were near-exact clones of their moms coming from? A magic mirror? Sure…why not?

As for Fifi, even though she is a unicorn, Baby Fifi is an earth pony (even though she has a different-colored streak in her mane like nearly all standard MLP unicorns have). Apparently something was wrong with the mirror when Fifi wished for her.

In fact, Baby Fifi is far from an isolated incident. There was a batch of mail-order baby ponies that were a different species than their moms: Baby Sweet Tooth and Baby Up, Up and Away were unicorns while their moms were earth ponies, Baby Milky Way was a pegasus while her mother was a unicorn, and their manes would always match the styles of their mothers.

Interestingly, unique baby ponies (i.e., ones that weren’t clones of the adults) started being released at almost the exact same time all these ponies were released. You could almost derive an in-universe explanation from that — the ponies must have started using the mirror less and less when it started producing “unfavorable” results…fortunately, this was around the same time that adult male ponies started to appear.

Fourth Row (left): An idea based on Baby Ribbs’ backcard story (which appears at the top of the panel). Baby Ribbon is there because she and Ribbs are so similar that they seem almost like siblings.

Fourth Row (right): Dazzleglow, the first intentional winged unicorn from G1.

In the My Little Pony and Friends TV series, occasionally there would be an animation slipup that resulted in a pegasus with a unicorn’s horn or a unicorn with wings. The most famous mistake is in the second MLP special Escape from Catrina, where Baby Surprise (a pegasus) has a horn for a couple of seconds.

However, though the toy version of Dazzleglow is just a unicorn, when she makes her sole appearance in My Little Pony Tales (in the episode “Up, Up and Away”), she is a winged unicorn. Dazzleglow is a Glow and Show Pony, and the other Glow and Shows are two earth ponies and one pegasus. In MLPT, however, they all have wings.

Their appearance in MLPT is a bit of a slap in the face, though — it’s as if the creators said, “So, the kiddies are whining about how there aren’t any unicorns or pegasi in our new show, are they? Fine — we’ll give them their stupid magic ponies!”, then created an episode featuring three pegasi and one winged unicorn, which were never seen or mentioned again. (And no, I don’t know what the deal is with an umbrella symbol being on a night/star-themed pony.)
