What the heck is she doing?

I have no idea.

Ah, "Baby Cakes", this is a fun episode! Don't have too much to say about it since so much of it revolves around shenanigans and physical humor, but I still got plenty of positive points to highlight, so let's begin.

First, I guess I'll start by saying that, out of all of Pinkie Pie's episode, I actually think that this one has the best lesson of all, if only because it's actually touching on a fairly mature subject: responsibility, in particular, the responsibility of taking care of children. This entire lesson is actually more contrary to Pinkie Pie's character than I think any other lesson she's had to learn in the show. Responsibility doesn't entail any partying, fun time shenanigans, R and R... in a word, anything that is Pinkie Pie's specialty. She loves spreading smiles and laughs, but to be honest, sometimes doing what needs to be done doesn't involve smiles and laughs (even if it can at times), just a lot of hard work, sweat, and toil, and that's alright, and Pinkie learns in the course of the episode just as much. The other thing I love about the lesson is not only that Pinkie jumps headfirst, especially in the second half, into proving that she's responsible, but also come to the mature realization that, despite her best efforts, it's OK sometimes to admit that you may not be capable enough to tackle something, even if you really want to. Overall, as funny as it is, this episode as I said before has a mature lesson that (1) responsibility requires putting in great work and effort and (2) sometimes despite our best efforts we still may not be fully prepared for something, but it's important that we know our limits and can admit as much. This is why it stands out to me as probably the best lesson Pinkie Pie's learned in any of her episodes, seeing as it's such a mature lesson and Ms. Pie is usually the anti-thesis of mature!

So what else works? Well, first of all, Pound Cake and Pumpkin Cake are a wonderful addition to the show's cast (who I wish would show up more often). They're adorable, it's interesting learning some about how foal's behave in the MLP universe, and the shenanigans they get into with Pinkie Pie are priceless. It's also nice seeing Mr. and Mrs. Cake get elevated in status as a result of their twins' birth; besides Shining Armor and Cadance and Rarity's parents, to date they're the only married couple we've seen on the show, and probably the most extensively seen married couple at that. It's nice seeing also their tackling the everyday responsibilities of parents and businessponies like a couple of pros, and this episode definitely raised my measure of them substantially. Finally, the humor... oh boy, this is a funny episode!

This is probably one of the funniest episodes in the entire show, and that's saying a lot considering how spot on the humor usually is in MLP. I like to describe the humor here as very Looney Tune-esque; there's a big emphasis throughout on physical humor and shenanigans, along with a solid blend of Pinkie Pie either talking to herself or the babies, mixed in with a few 4th wall breaking moments (of course... I mean, it is Pinkie Pie! ). The increasingly nightmarish babysitting gig is hilarious to behold as events spiral more and more out of control, and all in all it makes for just one heck of a fun episode, plain and simple. Overall, "Baby Cakes" is an extremely entertaining episode with a great lesson, great laughs, and some wonderful additions to the MLP cast. Not much else to say other than it's most definitely worth a rewatch if you're looking for some high quality entertainment and laughs!
