"I usually only get one present. From Twilight. A book."
While the moral was slammed into your brain with a giant sledgehammer wielded in the massive clawed fist of Spikezilla, it was a fun episode. Also, they gave the moral (relatively) subtly first before taking it on a town-destroying rampage.
"Pinkie, stop giving him cake!"
The moral, of course, is that you should never feed a friend's addiction, even if it's for something that seems harmless, because they can't stop themselves and they'll go completely out of control.
I actually expected not to like this episode from the synopsis, but it was good. n.n
