This is a type of "ambulate". Ambulates are almost like the "immune system" of the Living Fields. There are many different types but this is what is commonly known as a "basher ambulate". They attack hostiles by bludgeoning them with their grossly-enlarged and reinforced upper limbs.
Stench creepers infest the Living Fields and feed off of whatever biological material they come across, whether vegetable or animal, living or dead. They are akin to vermin such as rats or cockroaches in the Living Fields. They glide along on trails of pus-like material produced from bacterial colonies at the base of their bodies and give off an overpowering odor that drives off most predators.
