At the Dragon Den/The Orange Fire Dragon!

This is where the others arrive at the Dragon den, and where they encounter the Orange Fire Dragon in The Alliance of Berk and Equestria.

[We see some of the guards setting up some spears in the ground]

Princess Celestia: When we crack this mountain open, all dragons will come flying in tons.

Sharon: Ready positions!

Princess Luna: No matter how this ends, it ends today. [she then walks up to the mountian and gives the order for the guards to fire the cannons.]

[the cannon balls crack a huge hole in the side of the mountain]

Princess Luna: ATTACK!!!

[the equines prepare to attack but all the dragons fly out of the montain without ever raising a claw]

Equines: Huh?
