Here's how the mountain attack goes in Return of Darth Sidious
[we return to Canter lot and then Darth Vader comes to Sidious]
Darth Sidious: What brings you here, Vader?
Darth Vader: Master, I can feel the presence of Luke Skywalker in the Equestrian Mountains.
Darth Sideous: Send our new members to apprehend them at once.
Darth Vader: As you wish Master.
[A shuttle takes off followed by TIE Fighters]
Darth Vader; Master, I've also order them to bring back Princess Yuna back alive.
Darth Sidious: Good.
[we return to the mountain base]
[we see Snowdrop is practicing the Force]
Snowdrop: I see the ships. And the Millennium Falcon.
Eagle sight: [nudges her lightsaber]
Snowdrop: Yes. I see it. And you. [she then activates her lightsaber] Easy. [she then starts to levitate a small stone]
Snowdrop: [stops and then goes over to Yuna] Yes?
Yuna: Come on.
[they come back into the room with R2
Yuna: R2, contact the others.
[a hologram of Admiral Ackbar appears]
Admiral Ackbar: General Skywalker.
Luke Skywalker: Yes Admiral?
Admiral Ackbar: We need the dragon riders to lead the team to save Canter lot.
Yuna: You got it sir.
Admiral Ackbar: May the Force be with you.
[hologram cuts off]
Yuna: R2, now contact the Miner Trains.
[we see a hologram of the Miner Trains now]
Steam Claw D.: Miner Trains here.
Yuna: Good. We need your help.
Steam Mech: What's up?
Yuna: Mucker, we need your dragon mounted turrets, we're gonna need them for a possible battle.
Mucker: Right! I'll bring them right now.
[then at the side of the room, the turrets appear out of nowhere]
Nix; How'd you do that?
Mucker: We used our teleporter. Anyway, I'd do some test flights before you try fighting anything. That way you can be better aquantied with the turrets.
Yuna: You got it.
Mucker: Good luck and may the force be with you.
[hologram cuts off]
Yuna: R2, can you mount those turrets on our dragons?
R2: [beeping ("You got it, sister!")]
[he then rolls over to Night star and picks up one of the laser turrets and sets to work]
Yuna: Snowdrop, round up the other dragon rider and tell them what's going. Astrid will wanna be here to see Storm fly getting a laser turret.
Snowdrop: Got it.
[as Snowdrop leaves the room, R2 finishes mounting the laser turrets on Night star]
R2: [beeping ("Done!")]
Yuna: Good job. Do they feel okay, girl?
Night star: [nods]
[the others come in]
Astrid: Alright, let's fit one of those things onto Storm-fly!
R2-D2: [beeps and then picks up another laser turret]
Fish legs: Ready girl?
Meat lug: [growls]
[later we see all dragons have the turrets on their bodies]
Yuna: Mucker told me we should do some test flights first.
Astrid: Alright. Let's get to it!
[soon they are all fighting, as Fighting is Magic: Twilight Sparkle stage theme" is playing]
Hiccup: Alright, let's give these things a go!
[They fire at many of the set up targets. Then after several more times they get better and better at doing it]
Hiccup: Yeah bud, this is going just fine!
Yuna: How's it going girl?
Night star: [growls]
[soon after more test fights they become very good shots and hit all targets with ease.]
Astrid: Now we're ready for any possible battle!
Storm fly: [growls]
[but then an alarm goes off]
Rebel: Enemy forces heading this way!
Luke Skywalker: Get ready!
[we see the ships approaching]
Skyla: Heads up!
Hiccup: Alright, prepare for take off!
[the hanger doors open up and then the ships fly off]
Yuna: Take to the skies!
[the dragons then fly out too]
X-Wing pilot commander: Accelerate to attack speed!
X-Wing Pilot: Open wings!
[the wings open up and then the battle begins!]
[soon all ships are firing at each other and the dragons do the same]
Hiccup: We can't let them got to the base! Concentrate all fire at every enemy ship you see!
[The guns on Toothless fire]
[several ships go down]
Toothless: [fires his own plasma blasts at some of the attacking ships]
[Then an Imperial Shuttle is flying above the battle]
Yuna: An Imperial shuttle!
[It lands in the base]
Night star: [growls]
Han Solo: Be prepared for anything that comes out that door!
[the ship opens up and stormtroopers walk out and blasters fire at both sides]
C-3PO: Hide, R2!
[they then go into another room as Yuna and Night star fly back in to help out]
Yuna: [deploys the Lunar Saber and her own Lightsaber] [killing troopers]
Night star: [firing plasma blasts at troopers]
Yuna: [deactivates her sabers and then draws her plasma rifle and starts shooting troopers. But deploys them again]
[several troopers go down as Yuna battles them]
Night star: [roars and then continues killing troopers by blasting her plasma blasts at them]
[Then something else came out and then it was the possessed Sith!]
Yuna: [deactivates her sabers as they come out] Mama, Aunt Celestia, Cousin Cadance, Cousin Twilight, don't it's me!
Princess Luna: [darker voice] Hello, Night filly!
Yuna: MAMA!! IT'S ME, YUNA!! Your daughter! You need to snap out of it!
Princess Luna: [slaps her]
Night star: [looks back]
Princess Luna: [darker voice] Take her on board! The Emperor has so much work to do!
[the troopers pick her up and then take her in as the doors close]
Night star: [growls in shock and then she races for the ship]
[However, turrets fire at her]
Night star: [jumps to the side to avoid them and then the ship takes off] [mourns]
[the others then land in the hangar]
Skyla: Where's Yuna?
Night star: [sadly growls and indicates the Imperial shuttle]
Hiccup: They got her?!
Nix: We've got to save her!
Spongebob: Blackie! Get the Black Sponge star running!
Blackie: You've got it! [hops in their starship and starts the engines]
Spongebob: Han Solo? You better get the Millennium Falcon up and Adam too.
Han Solo: Never tell me the odds!
[soon both ships roar into life]
Han Solo: Hold on tight, kids!
[they both fly out of the mountain base]
Blackie: Now comes the fun part.
[both ships go into hyperspace]
