Zoombies don't always explode properly

[ZorkNemesis]

The Zoombies found in Agent Watkin's story arc don't always self-destruct when self-destructing.  The explosion still damages you and surrounding enemies (if it hits) but it seems like the explosion itself can outright miss the Zoombie who's blowing up.  They will continue attacking with their zombie vomit but presumably the self-destruction attack has a long enough cooldown that they won't get a chance to try again.

 

Incidentally Zoombies also lack a proper death animation.  If they die without exploding (or after failing to explode properly) they simply cease to exist rather than collapsing to the floor like their Embalmed cousins would.
