Why is the chimney thing that shape?
It's a spark arrester
https://en.wikipedia.org/wiki/Spark_arrestor
A spark arrester (sometimes spark arrestor) is any devices which prevents the emission of flammable debris from combustion sources, such as internal combustion engines, fireplaces, and wood burning stoves.
Spark arresters play a critical role in the prevention of wildland fire and ignition of explosive atmospheres. Consequently, their use is required by law in many jurisdictions worldwide.
