2013-02-21: Edited background, added shadows, changed the font and speech bubble.  
Comment on the edit: This is one of my first MLP “comics” I made of vectors I found in MLP-VectorClub galleries. I considered to delete this, but… after giving it a thought, I decided to make it look a bit better…
 
When we think about Pinkie teleporting off-screen, we need to decide on one aspect of it - does she teleport with a blink (like Twilight) or in a portal-like manner?
 
I actually like the second option more. What do you think?

Made in Inkscape and GIMP.
 
I edited the following vector:

Pinkie’s legs and tail were taken from this vector [link] by Thorinair

MLP and ponies belong to Hasbro and so on.
