Talk:28 Pranks Later/@comment-26423071-20160813204932/@comment-26423071-20160813214538

First of all, I'm talking about tone. "Bats" is one of the scariest episodes the show ever had, borrowing the tone of movies like "The Nightmare Before Christmas", "Corpse Bride", "Paranorman" and "Frankenweenie".

The tone of this episode remained lighthearted even during the "zombie" outbreak.

Second, back during "Griffon the Brush off", Pinkie spelled out loud and clear why ANYONE pranking Fluttershy is bad: Fluttershy is emotionally fragile and can't take a prank, so pranking her makes you a bully.

And Dash is Fluttershy's best friend. Dash doesn't seem to have any sisters, so Fluttershy is the closest thing she has to a sister. Their bond of friendship is strong. To quote Forrest Gump, they are like peas and carrots.

And now Dash is willing to break said bond of friendship just to be a bully to Fluttershy.

On the show that places an enormous amount on emphasis on friendship.
