0:35 - Twilight removed the light blue book from the shelf, yet it's back on the shelf when she drops all the books.

2:26 - Minor eye error on Rarity for about 3 frames.

2:30 - It appears as if the gem slot flips updside down while in the box between scene transitions.

5:24 - Spike has 2 "bodies".

5:40 - Pinkie is a BLANK FLANK!

5:53 - Someone else thought the candle on the door is a 3d object...or just got lazy with the door closing.

7:58 - There is an extra "basket" layered under Junebug's leg but above her body. It disappears and reappears abruptly.

7:59 - Spike's hands are reversed in 1 of the frames.

9:58 - Spike holds the blue book from the other end on the next scene.

*10:16 - Spike apparently took one of the (unactivated) Elements of Harmony.

12:04 - Twi xtra eyelash.

*13:07 - I can't really 100% confirm this one, but the way Scootaloo's tail is positioned suggests it's actually her(XTra long) mane...

13:18 - The broom clips through the top of the doorway for about 2 frames.

13:24 - Spike's left eye gets a green tint for some reason on 2 frames.

15:41 - Pinkie's a blank flank again, presumably because she's reusing the previous scene's "hindleg" (which was showing her inner thigh), except here it was reversed.

*15:47 - Spike's hand/arm is WAYYYY bigger than it should be. Not sure if I can really count this one.

16:24 - Colgate (Earth Pony Version) gets a horn on 1 frame after hitting Cherry.

16:28 - Spike's hand is going through his head on about 2 frames.

*19:33 - Is it normal that Spike's mouth is completely white? I guess it's supposed to be his teeth but it doesn't really work for me in this specific scene.

At 18:12, the wonderbolts cause dents on the giant water container. These dents are gone the very next second. But then, at 20:19, they're suddenly back.
