"Hello there. I'm Princess Luna."
"I'm Abblejack! And dat's Wainbo' Dash and dat's Wawity!"
""Pleased to meet you."
*Gasp!* "Aren't you that bad pony that's supposed the Sun Pwincess banished to da moon?!"
"Heh heh. Oh yeah... that. I figured I'd get some vacation time to myself and acted a little nutty so that Princess Celestia would send on a free trip to the moon for 1000 years. I sat my flank down there and did nothing, and she keeps track of all the royal busywork on her own, but when night comes she's asleep; so I'm free to wander around. When I 'return for vengeance' 1000 years later I'll just teleport Celestia to another plane for a few hours, freak a few people out, and get some ponies to 'exorcise' the evil out of me. It'll be fun."
"But, darwing! She banished
you to the moon! How did you get out of that desowate pwace?"
"I'm the Goddess of the moon for pete's sake. Banishing me to the moon is like locking a thief in a vault filled with gold bars, a guard uniform to disguise in, and a keycard to exit the darned thing."
"Well... I weckon that makes sense. Got any stowies for us while we're here?"
"Let me get some marshmallows out first."
