Smolder: Thut up.
Sandbar: And you still did it.
Gallus: Look at me, I’m mighty dragon. Watch as I bite through this rock in one go.
Smolder: Rrrrrrrrrrr
Gallus: Little did you know that “rock” was gabbro, one of the rocks Maud gave Professor Pinkie as a present. Pretty strong, eh?
Ocellus: And now you have to visit the dentist. Who even is the dragon dentist in Ponyville>?
Silverstream: Maybe Professor Fluttershy? She looks after loads of critters, it seems like it’d be her thing!
Yona: But Dragon isn’t critter. Dragon is Dragon. Maybe Princess Ember help?
Smolder: *grumbles* All theed do ith lath at me.
Sandbar: And it’d be rightly deserved.
Ditto. Although less pain :)
