I really do like her; for some reason she just makes me smile! :3 I'm happy you introduced us to all of your wonderful characters, seeing you do such amazing things with such incredible ponies, etc. really brightens my day; but every time I see Crackers I smile. X3
So long as it doesn't involve predestination paradoxes and alternates from parallel universes and alternates from a parallel universe who are also time-traveling in a predestination paradox that involves three separate realities. A.k.a the Bob and George School of "I ****ing hate time travel."
Seriously, time travel, it's just a big "No". As in, do not. Ever. No, not even once. Twilight Sparkle got off easy, she only made herself miserable for a week; whole realities have been unmade by careless time travel. Pinkie Pie is an example of that, or she would be, if reality ever had more than a passing acquaintance with her.
....ANYway. At least she appeared in a lovely popping bubble kind of thing. May I imagine it as having a "pfoof" sound effect?
Also, "Pony of the Future" sounds like Equestria's version of trying to imagine the future. "The pony of the future will lack magic, having come to completely rely on advanced technology!" Yanno, stuff like that. (Seriously, some "futurists" in the 1930s presumed that mankind's reliance on tools and advancement would eventually make us little more than oversized brain on atrophied bodies requiring machines to do something as simple as chew our food.)
And now I'm prattling. Sorry! Have some Crazy Train as recompense. (Ignore the video, just listen to the music.)
