There really is an xkcd for everything.

It's XKCD. A scientist who makes a comic strips, and this series is him answering questions, most of which are highly hypothetical, submitted by his readers.

Also, the idea of Randall Munroe of XKCD having to resort to clickbait is hilarious. He's gotta be in the top 10 most famous scientists alive.

That's not clickbait, that's you trying hard to be a pedantic ass.

It probably got turned into a black hole through the same method everything else happens in this series:

Magic. In the baseball video he specifies that magic is what causes stuff to happen, after the magic, it's all normal physics

To you, what is the difference between the moon being turned into a black hole and being replaced by a black hole with the same mass?

black holes can also be small, actually, it's based on a ratio of mass to diameter

You only need a high enough density of mass to form a black hole. You could take any amount of mass and in theory squeeze it hard enough to produce a black hole.

The sun is not massive enough for the astrophysical processes to form a black hole, but if you squeezed the sun into a small enough space by some magic it you could form them.
