There are certain LEGO building systems that are tailored to different themes and motives. Technic is most suitable for mechanization, System tends to be best for buildings, vehicles, landscapes and similar motives. Bionicle (character & creature building system, or Constraction, or whatever you may call it) was obviously intended to be used to build characters and creatures and not volcanoes! But LEGO fans love to use parts in unique ways and chubbybots‘ latest build is a prime example.
The build mostly consists of armor shells, probably connected on their intended limb pieces (or possibly in a different way, but we can not really see the inner structure). There are a few trans-neon orange chains for thinner lava flows and some round plates and bricks as smoke. But that is it. Such simple techniques were used in a unique way with a good sense of shape and topped off with good photography, resulting in a very memorable creation.
