A loud buzzing continued to fill the air around the stopped train, the black cloud above spewing forth flying things that begin assembling into aerial formations. The ponies on the train can see nothing about what's going on until the formations start divebombing the train...
"Quesadilla bugs?!?" Rainbow Dash exclaims as the first wave of attackers come into clear view, the bug-winged food shortly thereafter beginning to spit out what appeared to be balls of semi-solid cheese.
"This is worse than Twilight turning a frog into an orange!" Applejack exclaims, the cheese balls impacting the train with "sploot" noises and covering the train in cheesy gunk.
"Should we try to start the train again?" the train engineer asks Twilight Sparkle as the first bombing wave pulls away and a second one gets into position.
"Yes, but go at only the slowest traveling speed you can manage." Twilight answers as she tries to blast away at the approaching divebombers.
A few seconds later, the engineer disappears in the direction of the train's engine, and Twilight pulls her head back into the train after firing a few test shots at the diving swarms. The "sploots" of the second bombing raid impact the train as Twilight tries to figure out who could help her fight them off.
"Rainbow Dash, go out there and try to keep them distracted. Don't land on the carriage top if you can help it, that cheese is going to make it slippery up there." Twilight orders out before sticking her head out the window again and focusing on the flying attackers.
"Oh, oh, can I go too Twilight?!" Pinkie Pie eagerly asks, but is immediately whacked on the head by the folded-up umbrella Rarity had brought with her from Ponyville.
"No, all you're going to do is try to lick up all that cheese out there and slide yourself right off that train roof!" Rarity interrupts, her irritated expression and the blue-colored magic around the floating umbrella making it clear who was behind the parasol whacking.
"Darn, if I'd only remembered to bring my party cannon with me..." Pinkie mutters with a sulking attitude as the train whistle is heard and the machinery is put back into gear to get the train moving again...
-----------------------------------------------------------------------------------------------------------------------------------------------------------
Rainbow Dash zooms out the open back of the train and leaps into taking flight, looping back around toward the passenger carriage as she analyzes the situation around her. Below is a sheer drop toward rocky ground. To one side is the train lurching into slow movement again, Twilight shooting up bursts of magical energy toward a third wave of cheesy divebombers that fling down their loads despite the energy bolts "toasting" a few of the attackers, sending them plummeting down in smoking, crispy ruin.
"Ugh, I'm probably gonna need a bath when all this is said and done..." Rainbow Dash notes to herself as she zooms to catch the attention of one of the divebombing waves, easily outpacing the train now slowly moving across the truss bridge. Sure enough, she manages to catch the attention of the next wave of flying quesadillas that were setting up to divebomb the train, them switching targets to attacking her instead. She leads them toward the other side of the train, well knowing that the black cloud still above could harbor even more nasty surprises.
Meanwhile, back in the train itself Applejack announces she'll go up front and help the train operators in case they get attacked directly, leaving the other three Element Bearers with Twilight in the passenger carriage. Rarity, unable to do much to help the others in this situation, retreats to a corner of the carriage, dragging Pinkie Pie along with her; only once in the corner does she realize that Fluttershy is still sitting by a window, more out of morbid curiosity than anything else.
"Fluttershy, get away from that window! We don't know what those things are capable of!" the Generosity Bearer calls out when she spots where Fluttershy is.
"But maybe if I can just talk to one of them, convince them it was all a big misunderstanding..." Fluttershy quietly replies in her naive manner, pushing her window open against the dripping cheese as she does so.
It doesn't take long before one of the flying attackers - literally a floating quesadilla with fluttering bug wings and bug eyes that makes high-pitched growling sounds - drops down and hovers facing Fluttershy.
"Aww, hello little guy, maybe I can go talk to your friends and them it was all just..." Fluttershy starts before the floating food item spits cheese directly in her face before flying away to join the others in the next attack!
"MEANIE!" Fluttershy shouts as Rarity uses magic to yank her back into the train carriage, the window slamming down shut again.
"Pinkie, help me get this stuff off her face! It'll choke her if we don't!" Rarity shouts as she rushes up to Fluttershy, who is groping around with forehooves for something to clean her face off.
"Okie-dokie lokie!" Pinkie eagerly replies, bouncing up beside Rarity and beginning to lick the cheese off Fluttershy's face in the same manner a dog would.
Rarity, unsurprisingly, backs away in horror, bringing hoof to face as another round of gooey cheese bombs land on top of the train. And although Fluttershy's face is quickly cleaned off, the final result of her expression is the mortified confusion expected over the "tongue bath" she had just received.
"What? You said help get the cheese off her face, so I did." Pinkie defensively explains after finishing when she sees Rarity's extremely unamused look.
"Pinkamena Diane Pie, will you please start taking this situation more seriously?! These cheese-spewing things won't seem so funny if they derail our train!" Rarity exclaims in exasperation as the battle continues outside...
