I wanted to make an inexpensive Butcher for an upcoming game, and looking at the Ogre Bull sprue I figured out a way to make one without too much hassle. Here's what to do to create the mini pictured above:
First, construct an Ogre Bull body as normal, but leave the gut plate and arms off (arms will be added later).
The Butcher is going to look like he is eating something in mid gut-magic casting, so the bellower's head is perfect, plus it looks the fattest.
Next mix up a small amount of green stuff (around 1cm of the strip) and place it over the gut plate hole. You don't need to fill the hole just place enough over to make a belly bulge. Ogres wear their trousers over their gut, but since we're going to use loads of accessories don't be too worried about sculpting the trousers in the join of the green stuff.
