Freeze Frame Bonus / My Little Pony: Friendship Is Magic

• In the first episode, when Twilight is talking about Nightmare Moon and the Hourglass passes over the unicorn head statue in the background (around 4:50 into the episode), it changes to look like Nightmare Moon, going back when it is no longer behind the Hourglass.
• In "Griffon the Brush Off", when Rainbow Dash and Gilda race to a cloud, each claims to have been first, but Pinkie Pie claims Rainbow Dash won by just a little bit. To the naked eye it looks like a draw, with both arriving in a flash at the same time, but freezing the image at the right time shows Pinkie is right.
• In "Sonic Rainboom", when Twilight Sparkle casts the wing-making spell, an outline of Rarity with her butterfly wings appears for a couple of frames in the explosion of light, several minutes before we get to see the results of the spell properly.
• "Stare Master":
  • When her friends dismiss the broken table as who wants a hammer for a cutie mark, Apple Bloom looks dreadfully upset.
  • Just before Sweetie Belle starts singing, Scootaloo and Apple Bloom cover their ears.
• In "The Cutie Mark Chronicles", during Fluttershy's flashback, at the end of her song, if you watch the upper-left corner of the screen carefully, you can see Rainbow Dash just as she hits her first Sonic Rainboom. See here.◊
• In "Party of One", during Pinkie Pie's Sanity Slippage, her normal Genki Girl look appears in place of her morose form in single frames.
• In "Sisterhooves Social", Sweetie Belle runs a race with Applejack. At the very beginning AppleJack gets completely covered in mud and they run the race together, it's only until the end it's revealed that Rarity was really the one who ran the race. If you look back at "Applejack's" eyes you'll see that they're blue just like Rarity's, Applejack's eyes are green.
• In "Sweet And Elite", during Rarity's "Becoming Popular" song, close examination of the "talking portraits" scene reveals cameos from Hoity Toity, Sapphire Shores, Photo Finish... and Derpy with a paper bag on her head◊.
• "Secret of My Excess":
  • The dog anatomy pictures in the Vet's room all have the outline of Winona, Applejack's dog.
  • When Spike recovers his normal size and Rarity says "YOU were the rampaging dragon?" Spike grins and strikes a "let me explain" pose for half a second before plummeting to the ground.
• In "Baby Cakes", if you look closely during the opening, the babies in the nursery have the same or similar color schemes as other ponies, though most of them match more than one other pony (two that can be pinned down are the ones matching Rainbowshine and Medley).
• And in "Ponyville Confidential", when Diamond Tiara shoves Dinky Hooves (Derpy's daughter in fanon) aside, Dinky gets Derpy's eyes for a moment.
• In the episode "Pinkie Apple Pie", if you look closely at the right side of the screen at about the 17 minute mark, you will see a faceless, white pony wearing a suit.◊
• In "Maud Pie", when Maud saves Pinkie Pie, we finally get to see Maud's cutie mark for a split-second. Not surprisingly, it's a rock.
• "Equestria Games":
  • In the background crowd scenes, many past characters from the show can be vaguely seen, including Gilda, Sapphire Shores, Aunt and Uncle Orange, Gustave le Grand, Ms. Peachbottom, Coco Pommel, Cheese Sandwich, Octavia, the Mad Men ponies, Silver Shill, and many many others.
  • In the stands near the royalty box is a pegasus mare with Bulk Biceps' body shape and the atypical beehive hairdo, butterfly glasses, and a string of pearls necklace. She has been dubbed "Mama Biceps".
• "Twilight's Kingdom Part 1":
  • The necklace Tirek wears in the present is the same one Scorpan is shown wearing during their backstory.
  • Discord-as-a-pony's cutie mark resembles a cyclone or tornado. Appropriate for the spirit of chaos.
• In "Twilight's Kingdom Part 2", the cucumber sandwiches Discord offers Fluttershy are cut into the shape of butterflies, or Fluttershy's cutie mark, which makes it even more insulting when he drops them on the ground in front of her.
• "Slice of Life": Believe it or not, this appears for a split-second. Seems like the creators were having a bit of fun.
• "Marks for Effort": When Cozy is about to reveal to the Cutie Mark Crusaders she failed, she very briefly displays a smirk when she turns her head.
• "School Raze - Part 2": When the magic is being restored to Equestria, during the scene where Twilight and Rarity are getting their magic back, one ball of magic somehow absorbs into Pinkie.
• Derpy Hooves' cameos are sometimes this, like in "May the Best Pet Win", where she peeks out of Fluttershy's chicken coop near the end of the "Finding a Pet" song.
• This promo from the Hub riffs on the "There's an App for That" adds from Apple. Every pony app shown has an appropriately punny name and a matching icon (e.g. Wikiponia, Hooftube, etc.), proper use of pony terminology for various app functions, and even the "PNN" news article with tiny text which flashes by at the end is fully coherent and readable. Someone at The Hub obviously knew that that the Periphery Demographic would examine every frame for details like that, going so far as to give a Shout-Out to popular Pony Blog Equestria Daily.
