Here is my very first attempt at something I've wanted to do ever since becoming a brony. I could not pass up this opportunity, considering the timing of her line and the fact that she was against black.

No, it wasn't made with After Effects. I used Hitfilm Ultimate.

Consists of a key to remove the already black background, some motion tracking to match the movements of the camera, a mask for her eyes [due to the black key,] some fake camera focus, and some other little effects like the letterboxing.

I guess Rainbow Dash does not approve of my fish as a pet.
