The opening scene had a couple of things that were surprising to me....first how all the other ponies could really be that confused by Pinkie Pie giving out invitations in such a way, though maybe somepony never really does get used to Pinkie's ways...secondly Pinkie getting tired was a shock to me, since she usually doesn't ever show ne signs of slowing down..
Pinkie's Party: I found it funny how when Pinkie tells RD and AJ that there were more surprises in the bobbing for apples that RD just spits the apple off of AJ's head and she reacts to it, but doesn't really phase her, seemingly used to it with Dash. Similarly in the next scene where Rarity spits out the punch, but Pinkie has zero reaction to it. Also I do enjoy how Pinkie goes out of her way to make sure everypony has to deal with some kind of shanaigans at her party.
ITS SOOOOON!!: Applejack having the element of harmony, shows her skills at telling lies, by well be awful at it...which leads to absolutely great scenes between pinkie and AJ. Haha poor Spike....whats gonna work teamwork with dash and fluttershy leading to one of the greatest stories I have heard...starting with the drawn on watch by Dash.....hes a bear!!!!!!! (so pretty much if this wasn't already considered the best episode there ya go)....I really liked the fact that when Fluttershy and dash were trying to say what Harry was doing at the beach that on the third one they repeated what they had said the second time to try to get it right between the two....
hahaha Pinkie Pie coming to the conclusion that they were excuses is hilarious...
great disguise or greatest disguise? Its funny that they are being this secretive about the party, but in all seriousness to keep a secret from pinkie pie u almost have to and it doesn't even work.....SEE YOU LATERRRR.....enter RD and another Pinkie/Dash chase scene....haha I cant even imagine how Dash felt when she was in that bell....Pinkie using her head to knock on the barn and then welp give it another shot AJ...with some great construction noises...
7 hour bubble bath spike?.....AWWWWWWWWWWWWWWWWWWWWWWWW...when pinkie gets sad its really sad
Crazy Pinkie is one of my favorite scenes in the show....Poor Dash not knowing what she is walking in to.....and then arguing with a pile of rocks...
haha spike thinkin he is dancing with Rarity at the end....
im just gonna ignore Twilight's letter to Princess Celestia and just assume she has my best interests at heart
Overall this has to be considered one of the best episodes...the fact that it wasn't that hard to know what the entire episode was going to be about from reading the small description beforehand made me think that the episode had a potential let down aspect if the episode didn't have some sort of surprise and not be a surprise party, but the episode was still amazing even though the viewer was pretty much aware of what was going on from the start.
