Derpy Hooves is a happily-occupied mailmare. And as everypony knows, she's extremely fond of muffins. But for those rare instances in which she lacks a muffin to her name, she doesn't take it very well. So, one fine day, Derpy is both lacking in muffins... AND in money. Having no other option, the mailmare decides to get an emergency job at the local library.

Unfortunately, Twilight Sparkle doesn't have much need for yet another assistant; much less one that needs pay. So, to keep Derpy happy for a change, she decides to give her the only other job she could think of... let her keep an eye on a rusty old Time Machine that she just happened to have stashed away in the basement.

...What could possibly go wrong?

Written in my infinite boredom, another fic dedicated to everyone's favorite muffin-lover, and slightly more sensible than the last one I wrote. A two-part fanfic, so, expect Part 2 to come along soon. I might even do more with this idea later on, so who knows?
