The clue in the code talks about using it to avoid interacting with the different environments. It doesn't mention a water biome though, just swamps, lava, mountains and craters.

The coded message makes it sound like it'll be a flying/gliding vehicle. And it does look like one! 

A floating foundation? That would be nice!

Some sort of weapon! Perhaps a multifunctional device? 

And Halloween event has me too excited!

I have no idea what those droopy things are supposed to be or do. When I first saw the 2 at the front they looked like shriveled up little arms, it looked pretty funny

Looks to me like the big arms/legs hook into prey, and I guess then it starts sucking your blood? Maybe it drops down from above and wraps you in webs like Shelob

I thought most spiders sucked blood already.

They do I think, it's just that this has little leg looking things dangling as well as the big legs so it looks a bit like a cross between the two.

It's some sort of spider...maybe crossed with a mosquito?

So it is a fishing net, and apparently used to gather food. I wonder how big it will be? Big enough to catch a decent amount of meat I'd hope and therefore possibly useful for taming?

If it works like a bola and is large, maybe it can be fired from the ballista turret. Or maybe it will be most useful thrown from the back of the Turtle while hanging out underwater.

Edit: Might not be a fishing net at all, could be a passive trap used on land to immobilise creatures.

Well yes, I am making that assumption. Mysterious Mysterious have, in the past, always been about new dinos (correct me if I'm wrong) so while it is possible that this breaks the pattern I don't expect it to.
And, why do you think it can't move? It does have 4 legs, and all parts where the legs connect to the body are missing from the picture so there's no way to tell whether it can or can't from the picture alone.

I won't say you're wrong outright because I have no actual proof of it, but I think you are.
We know it's an anti-theft device, and it'd be pretty hard to deter thieves if it can't even move unless it actually is the storage container itself, or perhaps it shields storage containers nearby? Those are the two things I can think of where it could stay in one place.

I don't believe this is a creature, because the thread that was generated when the code was broken is titled "Equipment Test Record" and not "Specimen Observation Record" like the last one was. 

If it is a camera or scanner, I hope it communicates with HLNA so it can alert you while away from it.

It does look like it has cameras and/or lights on it, and the legs look a bit like a tripod. Perhaps it's something you can place like a security camera?
