Using "pegasus" to refer to an entire species of flying horses rather than the specific Greek character, "Pegasus", is a more modern development.

Answers.Body: <p>It doesn't look like there's currently any way to make this connection by normal means.</p>
  
  <p>While there are quite a few parts with similar 1.6 mm attachment holes as your daughter's horse has (including some mildly surprising ones like <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=93081b&amp;name=Friends%20Accessories%20Beetle%20/%20Ladybug%20with%20Stud%20Holder&amp;category=%5BFriends%5D#T=C" rel="nofollow noreferrer">this ladybug</a>), parts with the matching pins seem to be relatively few.  Basically all of them seem to be small ornaments like <a href="https://www.bricklink.com/v2/search.page?q=plume&amp;brand=1000&amp;cat=636&amp;tab=P#T=P" rel="nofollow noreferrer">minifigure plumes</a> and <a href="https://www.bricklink.com/v2/search.page?q=with+pin&amp;brand=1000&amp;cat=636&amp;tab=P#T=P" rel="nofollow noreferrer">other headgear accessories</a>, including some <a href="https://www.bricklink.com/v2/search.page?q=with+pin&amp;brand=1000&amp;cat=771&amp;tab=P#T=P" rel="nofollow noreferrer">Friends accessories</a> like your bow.  And as far as I can tell, none of them are really suited for attaching further parts.</p>
  
  <p>Screwdrivers, as <a href="https://bricks.stackexchange.com/a/13069">suggested</a> by Rin Rio-Oki, probably won't fit: the shaft is slightly too thick, as you can see in <a href="https://i.sstatic.net/5pilS.jpg" rel="nofollow noreferrer">this composite photo</a>.  The tips of <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=3741&amp;name=Plant%20Flower%20Stem&amp;category=%5BPlant%5D#T=C" rel="nofollow noreferrer">flower stems</a> <em>might</em> fit, but even if that worked, it'd just look totally ridiculous.</p>
  
  <p>So you'll probably have to resort to some "blasphemous" methods.  In that respect, I see two options worth considering:</p>
  
  <ol>
  <li><p>Filing the base of your unicorn horn down to about half of its original diameter, as <a href="https://bricks.stackexchange.com/a/13073">suggested</a> by BlokeDownThePub, should let it fit into the hole.  It'll be tedious and fiddly work, and you could easily end up ruining the part entirely if you're not careful, but with practice it should be doable.  Of course, this also means that you won't be able to use the horn for its original purpose any more — although there are plenty of parts that should be able to make the connection in <em>that</em> direction, like the <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=20482&amp;name=Tile,%20Round%201%20x%201%20with%20Bar%20and%20Pin%20Holder&amp;category=%5BTile,%20Round%5D#T=C" rel="nofollow noreferrer">Round 1x1 with Bar and Pin Holder</a>.</p></li>
  <li><p>You could glue the horn to a part that already has a suitable pin, as you yourself suggest.  While you <em>could</em> use the bow you already have for this purpose, I'd suggest trying a <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=93080f&amp;name=Friends%20Accessories%20Hair%20Decoration,%20Star%20with%20Pin&amp;category=%5BFriends%5D#T=C" rel="nofollow noreferrer">Star with Pin</a> accessory instead:</p>

  <p>If the 3D models are anywhere near accurate, the base of the horn ought to just fit inside the star (although not all of it; it's too long).  Alas, it probably won't <em>stay</em> in without glue, but at least it may <em>almost</em> look like a legitimate connection.</p></li>

And as far as I can tell, none of them are really suited for attaching further parts.
  
  Screwdrivers, as [suggested](https://bricks.stackexchange.com/a/13069) by Rin Rio-Oki, probably won't fit: the shaft is slightly too thick, as you can see in [this composite photo](https://i.sstatic.net/5pilS.jpg).

  So you'll probably have to resort to some "blasphemous" methods. In that respect, I see two options worth considering:
  
  1. Filing the base of your unicorn horn down to about half of its original diameter, as [suggested](https://bricks.stackexchange.com/a/13073) by BlokeDownThePub, should let it fit into the hole. It'll be tedious and fiddly work, and you could easily end up ruining the part entirely if you're not careful, but with practice it should be doable. Of course, this also means that you won't be able to use the horn for its original purpose any more — although there are plenty of parts that should be able to make the connection in *that* direction, like the [Round 1x1 with Bar and Pin Holder](https://www.bricklink.com/v2/catalog/catalogitem.page?P=20482&name=Tile,%20Round%201%20x%201%20with%20Bar%20and%20Pin%20Holder&category=%5BTile,%20Round%5D#T=C).
  2. You could glue the horn to a part that already has a suitable pin, as you yourself suggest. While you *could* use the bow you already have for this purpose, I'd suggest trying a [Star with Pin](https://www.bricklink.com/v2/catalog/catalogitem.page?P=93080f&name=Friends%20Accessories%20Hair%20Decoration,%20Star%20with%20Pin&category=%5BFriends%5D#T=C) accessory instead:

     If the 3D models are anywhere near accurate, the base of the horn ought to just fit inside the star (although not all of it; it's too long). Alas, it probably won't *stay* in without glue, but at least it may *almost* look like a legitimate connection.

  I'm very late to the game here, but why can't we use the existing hole as a guide for an appropriately sized drill bit, converting it from Friends accessory size to standard LEGO horn size? If you drilled it slowly by hand, it would be really hard to mess it up.

  > **username_13**: I see coule of issues here: 1) drilling isn't a solution for purists; 2) not sure if such drill bit exist to create a hole of 3.18 mm in diameter.
