Puke Worms are secondary enemies introduced in SAS: Zombie Assault 4, that somewhat resemble leeches, and are generated by Regurgitators, which puke them to attack the players. Except in the aquarium on the mission VIP, there's no other way it can be encountered. Just like other regular enemies, they have Regular, Fetid, Evolved, and Apex versions. Puke Worms also possess the Regurgitators' buffs if spawned by them.
They also appear in the mission VIP as a hidden enemy within a fish tank, appearing when aforementioned prop is broken.
