Ah, I am happy to see that I am not the only one here that loves Inuhoshi's drawings! This is one of the older comics that they have released on their DevaintArt page (and was subsequently released to Derpi), and there has been a few more that was released since this one was drawn up. Nonetheless, Mayhem is always fun to see, and this is a fun example of just how unpredictable he really is. Really, he is the type of creature that only Fluttershy could love, and I do hope that she helps guide him into actually being a respectable creature in Equestrian society, much like his father ended up being.
I'm currently uploading my favs from derpi here, so you may see some older stuff from time to time :D
