Castle Sweet Castle (My Little Pony: Friendship is Magic)

Castle Sweet Castle is the third episode of the fifth season of My Little Pony Friendship is Magic and the ninety-fourth episode overall. The title is a play on the phrase "Home sweet home."

Plot
After finding out Princess Twilight's been avoiding her castle, her friends try to make it feel more like home

Why It Rocks

 * 1) The episode is a pretty good follow up to Twilight's Kingdom, with it showing the aftermath of the destroyed library.
 * 2) It perfectly portrays how one would feel from the destruction or mere departure from their old home and having to get used to a new one, as Twilight is overcome with feelings of sadness and nostalgia mixed together, no matter how great her new home might be.
 * 3) The episode includes an emotional scene of Twilight and Spike visiting what was left of the Golden Oaks Library.
 * 4) It once again demonstrates how well-meaning Twilight's friends are. When they find out that Twilight is avoiding the castle, they attempt to make renovations to the castle to make it seem like home, to the tune of a the lighthearted song "Make This Castle A Home".
 * 5) Following this, the episode teaches a great lesson about the fact that what may seem like home for you won't seem like home for another person, and thus teaches that it's good to think about the person first, as Twilight's friends actually decorated her castle with what seemed like home to each of them rather than Twilight. It also teaches that a little redecoration doesn't cover up memories.
 * 6) Some comedic moments, like when Twilight washes Angel Bunny too much and when Spike asks for firm massages.
 * 7) The ending is perfect, with the castle being decorated with gems that depict a memory in Twilight's life, and Twilight getting ready to make some new memories.

Bad Qualities

 * 1) Twilight's friends are a little unlikable in the small conflict after the decoration of the castle, especially Rainbow Dash.

Trivia

 * The episode was initially teased by the show staff at the 2014 San Diego Comic-Con.
 * This is the first episode to mention the name of the Golden Oak Library, previously called that and other names in a wide variety of materials years earlier.
