This is something I doodled after I thought of combining pinkie with a companion cube. I then vectored it to improve it. This is my first attempt at a vector so apologies for any flaws. Hope you like it.
Just a thought: it would be so funny to see Fluttershy sitting there next to the Aperture Science Emergency Intelligence Incinerator, crying over having to "euthanize" her Aperture Science Weighted Faithful Companion Cube. And I'm sure there's a joke about Applejack and exploding lemons in there somewhere.
