i came here expecting to read at least one smart ass reply. i was not disappointed.
On topic: if you search the net for a manga or comic booru that appeals to the type of comic you're looking for, i image there wouldn't be too many results for "achievement" you'd have to dig through. Remember all the key words you can think of try that. Do you have even a single image taken from said comic? if you did, you could find the rest by reverse image searching via Google. A quick Google for "furry comic xbox achievements" got me this. Any luck?
