How Ponies Reproduce

My theory on pastel pony reproduction is that there's a magical human, riding a flying sleigh that is being pulled by four malnourished slaves.

The magical man is obese, because his slave does all the dirty work for him. He wears a red clothing, mostly covering his ass. He has a big sack, placed on his sleigh which holds all the foals.

Now, this where foal comes from. When a couple wants to have a foal, they close their eyes and make a wish. While their eyes are closed, there's a nearby bee that will sting a bird so hard, it will scream beyond imaginable.

Then, the magic man -- from Adventure time  -- will appear in front of the couple, giving them the foal that they desire. After that, the magic man visits the magical man, and he will tell all of the good deeds he did. Then the magical man will give magic man some weeds in return.

And that there, my friend, is how foals were made.
