The episode's about Twilight being sent by Princess Celestia to their old castle to find a book that will help find research about the box. At the same time, Rainbow Dash and Applejack are having a most daring dare competition, Pinkie Pie being the judge. After a fail attempt with being covered by bees and ending in a tie, they take their challenge to the old castle to see who could last in the "scary" castle the longest. Pinkie Pie heads off without them to ring the town's new school bell for them. Meanwhile, Rarity and Fluttershy head to the castle because Rarity wants to retrieve old cloths to make them into new fashions.
When all of the ponies are there, they face the many secret trap doors and booby traps (hehe....booby) that lie within the castle. Twilight, of course, is left in the library reading books (insert twilight books face here...) and unaware of the other ponies in the castle. Spike does mention that he hears noises, but Twilight ignores it saying "it's an old castle. Nightmare Moon destroyed most of it and it's falling apart." During this, the other ponies happen to see a hooded pony lurking around the castle. After some time, the ponies all meet up, not knowing at first and freak out when they think the other ponies that bumped into them are something attacking them. After Twilight freezes them and sorts out the situation, they investigate a noise that sounds like an organ playing somewhere in the castle. They come to find the hooded pony play the organ. Twilight walks up to the hooded pony and finds Pinkie Pie being the hooded pony. Pinkie tells them that after she rung the school bell, she wanted to do a finish ringing the school bell party and went to the everfree forest to pick blue bells, but then she was cold. So she used her tarp to keep her warm. She saw Fluttershy and Rarity and followed them to invite them to the party, but then everypony ran from her and she decided to make an "Everypony go to the scary castle and run away from each other while Pinkie played the organ" Party.
In the end, the mane 6 gathered up in the library. After some conversation, Rainbow Dash asks Twilight why she wasn't afraid. Twilight says that "knowing something in the past made it easier to deal with in the present." That phrase gave Twilight the idea to start a new idea for the mane 6 to make journals about learn from each other about their stories and experiences.
My thoughts about this episode? It was pretty good. Not on my top favorites, but it was pretty good.
I like the CastleVania joke they made for the episode title, but it seemed more like a Scooby Doo episode or like Luigi's Mansion (Stole Luigi's Mansion idea from Sorry, Nykkes! ), or in general just any mystery castle movie. For the story line, it was played out evenly and very well placed. Each pony were equally given air time. The joke in the episode were really funny. I especially loved when Rarity and Fluttershy were stuck in a closed in dug-out and rarity tried to reach for a hole and she touched Rainbow Dash, but both thought that they were being touched by some monster. Then Fluttershy tries and hits a switch and frees them. I also loved when Fluttershy tries to grab the tarp and the wall flips around and Applejack sees the tarp moving and gets scared. Then Fluttershy comes back and Rarity tells her and Fluttershy never even knew
Now for characters, I want to try a new way to review them. Well not actually new, but new for me. I saw this idea from a while back when he reviewed Season 3 and I want to try it:
& : These two went back to doing what they did back in the "Running of the Leaves" episode. More friendly competition like, but still very competitive. It brought back the good ol' RD and AJ rivalry.
Also, the duck noise AJ makes makes when she shakes her head from coming back from a trap door was hillarious!
& : Of course I'm going to say that I loved these two, considering I love these two ponies, especially rarity! Fluttershy was just shifted into maximum overcute in this episode and Rarity went full blow awesome and adorable in this episode. I don't think I need to say anything else about them besides saying that they make the best partners.
: She.......Didn't get a lot of air time actually. Though she did have some very funny moments like usual, there wasn't a lot. It could be because she had so many episodes with her being involved a lot in them and they wanted to focus more on other ponies for now. I'm sure Pinkie will be back and breaking the fourth wall for us more often again soon.
: One word. Books......That was pretty much her episode. Finding a book......Wow! Such knowledge! Much reading! Twilight Doge!
I'm sure they're going to give Twilight more episodes soon.
All-in-all, it was a pretty good episode. It seemed more focused on Applejack, Rainbow Dash, Fluttershy and Rarity. I think it was well deserved since Pinkie Pie and Twilight tend to get a ton of episodes. Also the quality of the shows look far better than when the show started. They've improved much more into the detail of the show since it started. I feel that this season has started pretty darn well and it's going to get even better!
