How about this guys? We can't tell if the nose is really possible for us - we don't even have dimensions on this 'log'. It could be 2 feet long, with correspondingly narrow nostrils, to narrow for us. Or it could be 20 feet long... and we'd fit pretty easy.
We can eat organic matter, and we couldn't eat through it's hide. It wasn't a log, maybe it's not even a (biological) crocodile.... maybe it's actually a robot or something.
There's SO much we don't know... Heh, my plan for 'go back and get us some grub' that we wasted an entire hunger point on, and that so many people agreed with, was totally based on the assumption that the mice around our centipede were similar to the mice we players know; unable to think like an organized and delegating defensive army without individual curiousity ( it takes some serious self control or some serious obedience to outside orders to NOT go investigate something new that seems nonthreatening/dead.... our mice will walk right up to an unmoving snake to check it out after a time.... this world's mice are SUPER different and unnaturally organized and careful.... for all we know, we EVOLVED here and all these critters have evolved to survive being hunted by stuff exactly like us
)
Right, back to the point.... We actually don't know yet what our best plan of attack for this beast is. It could be the nose, the mouth, the... unwanted option that I won't name again, or a wound we don't even know it has... maybe even the 'earlid' that crocodilians posses and the very thin tympanic membrane that are the only barriers keeping us out of its ears will prove to be a great opening for us.
So... I suggest that we explore the log and let 'it show us' where we can attack it best. Or let 'it show us' that that's a bad idea.... and if so... we move to plan B, which might be to drift away from our AWESOME (and AWESOMELY ARMORED) meal, and accept the vegetation that we're getting carried to.
Move slowly along/around/over the log, searching for a natural opening into it. Move inside to feed.If there's just no place to enter our ride, or it isn't actually organic material, plan B:
When close to the opposite shore and its vegetation/debris, drift from the log towards this organic material, and start to consume
