Due to certain experiences within the Dreamlands, Felix identifies more with the Gugs than with the humans. So when the young, untalented, noobish sorcerer found a spell for shapechanging, he immediately adjusted it to turn himself into a (human-sized) Gug. Unfortunately for him, he forgot to factor in that Gugs are mute, and constantly eating.

I personally like how it came out. The anatomy checks out, the pose is probably the best I've ever managed... I am proud of this one.

Felix and the picture are mine.
