Pinkie asks Applejack if she’s a chicken, when she’s the only one of her friends to volunteer to go on the coaster with her. That seems a little silly.

@Abominationalist  
no wait! i see what i was misunderstanding! in the first and last panels, the same drawing of the characters in the car is used, making it look like it’s the same characters in both panels, making me wonder why firefly, surprise, and posy are suddenly there, but that’s not the case!  
in the first panel, the ponies in the car are just some background characters, while fluttershy, pinkie pie, and rainbow dash are looking at the roller coaster.  
in the last panel, the ponies in the car are pinkie pie and applejack, while firefly, surprise, and posy have now approached from off-screen.

Pinkie’s presentation of the nail (apparently) taken out of the roller coaster suggested a potentially life-threatening structural failure, and consequently scared Applejack white as a sheet.

Last Panel: Meanwhile, with Surprise, Posey and Firefly…

I don’t get it…

@ZeroSpawn47  
Compare it to the first panel: it’s exactly the same composition, only with different colors (because Pinkie is on the rollercoaster and Fluttershy and Rainbow Dash are, presumably, doing something else). The more things change, the more they stay the same.

completely lost me on the last pannel

The roller coaster went so fast they traveled back in time!

I would be too, like in tight spaces, sometimes I like em, but if it becomes a little TOO difficult to get out, I start to get claustrophobic.

Interesting thought: Dash has no problem with that kind of speed when she’s in control. Strap her to something that she can’t control, and she gets scared.

@Playah  
That’s a bit mean spirited of Pinkie, don’t you think?

@Evowizard25  
Think she’s making AJ think she removed/found an important part of the ride.

What’s with the nail?
 
And honestly, I never liked roller coasters. Yeah, I’m a scaredy cat. I’m not afraid to admit that. {But doing that with the person next to me holding a nail, no way.}

Why is RD wet?

Pinkie, ya li’l punk

I did that once.
