There was a picture. It got put up on Nintendo site or something by accident and then removed, if I'm not mistaken? It was yellow, had purple stripes on it's arms and stood upright on two legs.
EDIT - If you go on Google images and search Espurr, it's the very first picture that comes up with Fletchling and Pancham. It might be fake, but apparently (not sure of the source :/) it was put up and then removed from an official site (either Nintendo or Pokemon, I forget)
It's FAKE, guys.
I can tell that it's not Sugimori's. Sugi has a unique way of drawing lineart and shading.
The yellow cat was a lame attempt to copy Sugi's style.
It's also a bad Photoshop. The person who did this forgot to put a drop shadow.
I can't believe I forgot to put that in the Rumors and Fake Scans thread...
Added.
