Where did the fluffle puff came from?

[~Silver Essence~ 2,622]

So, question that brought up my mind recently is the true origin of this creature.

Now, I find this thing adorable and hilarious in both it's tumblr and recent videos, however, I want to know where exactly did this thing originated from.

If I remember, the first time I saw this thing is in MadameLeFlour's youtube video, Magic PMV, in the background behind the living tombstone.

So does anyone know where did this came from?

PS: I know it's a silly question, but I am curious....

It was on tumblr first, I'm not sure who did if first per se, but I know it did originate from tumblr.  But you have to admit, those videos are amazing.
