Luna, Trapped [spooky]

>Luna do you have moment. I want to talk to you about something.
>Yes, sister. Has a problem arisen?
>No, nothing too major. I was wondering if you had any plans this Saturday.
>Neigh, my schedule is clear for the next fortnight. Why do you ask?
>While I was wondering if you wanted to make a public appearance in my stead. I am attending a meeting with the delegation for Saddle Arabia on that day, but this invitation arrived today.
An opened letter levitated towards Luna. Luna took it from here sister and inspected the front. It was addressed ‘To Her Royal Highnesses.’ Luna opened the letter and read it. She blinked confusedly before reading it again.
>What is this an invitation too?
>I think its to an amusement park.
>What is an amusement park?
>Its like a permanent carnival. Its a place full of rides and games. Ponies go there to have fun.
>Oh, I like fun. I shall RSVP immediately.
Luna gave the letter one last fleeting look, but still didn’t understand what it exactly meant. All it said was, ‘You are cordially invited to the inaugural voyage of Mister Bone’s Wild Ride.’
