Cue the scooter appearing in a flash of blue light as its skids to a stop  
Seeing the scooter, Rainbow Dash approaches it slowly. As she approaches, the exhaust vents on the back of the Scooter release a plume of white smoke. In addition, the Scooter is covered in a thick sheet of ice. Tank is also covered in the ice, with his head and limbs hidden inside his shell. Rainbow tries to pick Tank up, but drops him as she recoils in shock.
 
“What? Is it hot?”
 
“It’s cold! Darn cold!” Rainbow picks Tank up with her wings, to which he pops his head out
 
“Haha! Tank, you little devil!” checks the watch around Tank’s neck “Tank’s clock is exactly one minute behind mine and it’s still ticking!” Puts Tank down and lets him fly off to the side
 
“He’s alright!”
 
“He’s fine! He’s completely unaware that anything happened. As far as he’s concerned, the trip was instantaneous! That’s why his clock is one minute behind mine! He skipped over that minute to instantaneously arrive at this moment in time! Come here! I’ll show you how it works!”
 
Hops onto the scooter
 
“First you turn the time circuits on.” Flips the switch, and the time circuits flicker to life

“The way I see it, if you’re gonna build a time machine into a scooter, why not do it with some style? Besides, the stainless, plastic construction made the flux dispersal-”
 
Watch Beeps  
 
“Look out!”
 
(Imagine the scooter in the car’s place)

Twilight seems more the type of pony for this picture.

The rainbow fire trails are nice touch.
 
Not sure if I see Dashie being “eccentric” enough to be the Doc. (Twilight, or Pinkie would be more suiting.)

Oddly enough, I actually read that in Rick and Morty’s voices.

“Ha! What did I tell you?! EIGHTY-EIGHT MILES PER HOUR! The temporal displacement occurred exactly 1:20 AM and zero seconds!”
 
“Sweet Luna! Dash, you just disintegrated Tank!”
 
“Calm down, Scoots. I didn’t disintegrate anything. The molecular structure of both Tank and the device are completely intact.”
 
“Then where the hell are they?”
 
“The appropriate question is, ‘When the hell are they?’ You see, Tank has just become the world’s first time traveller! I sent him into the future. One minute into the future to be exact. And at precisely 1:21 a.m. and zero seconds, we shall catch up with him and the time machine.”
 
“Wait a minute Dash, are you telling me you built a time machine… out of a Scooter!?”

I forget the context of this picture.

She did it! She made Tank travel through time!
