SNEK DO A SMOOTH SMOKE
A long time ago in a tomb far, far away...
Some cobras were like, "Guarding gold is for losers. What if we got... high?" Ancient magic happened. Now they hold cigars in their mouths (somehow). No lungs? No problem. They don't care about your curses. They only care about that sweet, sweet smoke.
They are the CEOs of Hot-Boxing the Afterlife. 3,000 years, no lung cancer, just pure swagger. This is the peak of reptilian evolution.
