On the Physiology of... the Otyugh - Part Five.

Inside and out...

Two areas will be considered in today's update. First of all, the mouth. The Otyugh is described as having a sucker-like mouth that's full of teeth, and one or two of my previous scribbles have suggested how this might look. The scribble below goes into a bit more detail:

If we run with the idea that Otyugh is a sort of dungeon hoover, this area would usually be busy chowing down on various nasty things. At the same time, this also suggests that the whole mouth and throat is like a nozzle and a pipe - only a lot more dangerous. It also occurred to me that the mouth and teeth might be able to extend a little in order for the monster to get more of a bite, and this is what I've suggested in the lower part of the scribble above. The overall look is a cross between a pig's snout and a shark or lamprey mouth. If we zoom in on the only solid part of the whole area, a tooth looks like this:

The idea here is that the teeth are scooped shard-like pieces arrayed inside the mouth. These would act both to cut and perhaps also to rotate backwards from the root to convey it's food into the mouth. Imagine hundreds of these teeth acting in unison and the Otyugh seems more like a garbage disposal unit - which is effectively what it is.

The second point for consideration is how the monster might appear under the surface. I don't imagine the Otyugh having a skeletal structure in any practical sense:

Instead there's a main spine-like cartilaginous mass running along the top of the body, which is flexible but tough and acts as an anchor point for both the internal organs and the outer muscle layers. You can see more of this in the cross-section detail below:

Seen from the front: (A) skin/hide (B) muscle layer (C) internal organs

The upper left of the scribble is a section of the 'spine' as seen from the side; the detail in the bottom left shows the underside of a spine section with the tendon, etc attachments to the internal organs. The greater mass of the Otyugh is still fleshy lumps of muscle and organs. The spine, teeth, eyes and tentacle edges are made of tougher, solid stuff but the overall design is still one which is both flexible and resilient.

Next up for consideration is how the muscle mass might work and be arranged around what I've shown in the above scribbles...

More monster scribbles...

While the Otyugh stuff is on hiatus (I need to do some more scribbles of it's internal structure), here's a pic of a Gnoll...

... and a Bulette:

I like the Bulette because, as with the Otyugh, it's a bit of an oddity. Mind you, I've not put much thought into getting the details right (i.e. the armoured bits). It's just interesting to play around with as a design. If anything, I need to stress the 'armoured armadillo' vibe of it some more.

As for the Gnoll, it's another D&D creature that I find interesting. They're a bit more uncouth and raggedy than your average Orc, Kobold or Goblin. The only problem area with design is how much the neck should extend from the shoulders. The hyena-like features would suggest a longish neck, but I'm not sure yet if it looks right. I think I need to do more studies of hyenas to get my Gnoll looking less like a dog.

On the Physiology of... the Otyugh - Part Four.

Eyes

As the Otyugh is a weird creature, with a pair of eyes on a stalk and an aversion to light, one idea that came to mind was whether those eyes are actually anything normal. By 'normal', I mean whether they would be like an animal eye, with a similar lens, retina, etc. My line of thinking was continuing along with the idea that bits of the Otyugh are 'solid' in some way. A few themes could follow this; namely, whether the eyes are compound and also if they might be formed from blobs or clusters.

As you can see from my previous scribbles, I've suggested that there are blobby bits at the end of the eye stalk. If we zoom in on just this area, one concept was that the eyes are within the stalk and are made up up of several smaller solid sections:

You can see the aforementioned blobs, with nerve strands leading away down the stalk. Zoom in a tad more, and things start to look like this:

The picture above shows how the blobs are clustered within the left and right sides of the stalk, and I've included a side view of one blob. When I say 'blob', the idea was really more along the lines of them being solid in some way, and sensitive to light - but perhaps too much, hence their photophobia. One visual that fed into this design was the way things look when you slice a gooseberry in half:

Note the veiny bits leading to the seeds

Why a gooseberry? I dunno. Perhaps it's the way transluscent and solid mixes together. As I've said before, this mixing is how I imagine the Otyugh's overall look.

Anyway, another approach might be that the solid parts of the eye rest on the surface of the stalk. One interesting creature that uses minerals as the basis for a kind of eye is the chiton. Perhaps the Otyugh could have something similar, at least in the sense of those blobs being more like encrusted, light-sensitive primitive eyes formed from some sort of solid matter:

The scribble above maybe has things looking a little too conventional, but with the fourth drawing I was also thinking about the ways those solid bits might work as a single cluster.

This last scribble mixes the above concepts together:

The idea with this is to have a rough faceted look, either like coal or roughly worked flint. I've drawn an individual blob just to give some impression of the idea I'm trying to get across.

Still, I've not settled on a final look - although I tend to gravitate towards the look and feel of the last scribble. I also like the idea of the being able to see the nerve strands within the eye stalk. Maybe perhaps if the tip of the stalk was a little more opaque and was pigmented with various disgusting hues, it would help with camouflage when the Otyugh is hidden away...

On the Physiology of... the Otyugh - Part Three.

Tentacles...

Here's a pencil scribble in which I try to out flesh out the overall shape of the Otyugh a bit more:

This is starting to move along the lines of how I envisage it might look, although the design is still evolving. 

As the Otyugh is described as having a pair of ridged tentacles, one is issue with this might be about how it can move along as it eats it's way through dungeon crap. When on the surface, this may not be a problem, but I was wondering whether they might sometimes actually be more of a hinderance than a help. One option might be that it drags its tentacles along with it as it moves, like this:

That might not always be practical. One thing that occured to me was the fact that the ends of the tentacles, being sharp, may be more like some sort of chopping/digging/cutting tool, as well as being weapons. The reason this popped into my head was from prior experience of... er... crap. Many moons ago (when I was 16, in fact) I got a part-time job helping to do maintenance work on a small-holding (a type of small farm). One of my main tasks was to herd goats from their covered pen each morning to a nearby field - I also had to herd the bloody things back again at the end of my shift. Another task was to clean out the pen. This wasn't a simple case of just chucking down some straw, oh no. My employers asked me to clear out all of the accumulated crap that had been there for years. This meant I had to chop down through a 2-foot deep layer to the concrete floor beneath. This was no easy task. Compacted years-old goat crap is very resilient, I'll have you know. I had to use various implements (fork, spade, hoe and shovel) just to make any sort of dent in the upper crust. Not all that much fun, as you can probably imagine. Don't try to imagine the smell as I broke through the surface either. This was all done at the handsome rate of £1.25 an hour for my troubles. I must've been bloody mad.

Anyway, the long and the short of it is that the Otyugh may possibly have to contend with similar trials when chowing down on dungeon crap, especially if it found a compacted layer in some dark corner somewhere. Perhaps it would need to chop its way through, thus leading to it evolving sharp edges to its tentacles - a handy adaption, as it also helps with defending itself. This might also mean that it would need to retract its tentacles when chopping and eating its way along:

Hmm - but maybe this makes it a little too seal-like...

With that in mind, I had a go at scribbling a few different ideas for how those sharper bits might look.

There's the spiny, curved profile theme:

Or variations on the 'chopping' theme:

I've yet to make up my mind which way the final design might feature these appendages.

Next up for consideration: the eyes...
