I’ll give you the official explanation. When Snarks are released, they go into a frenzy and after about 20 seconds they completely overload themselves and burst.
While they do show signs of aggression and distress while being held, they cannot run, or bounce around and therefore do not get so worked up.
As for giving them health and making it so that you have to kill them, forgive me for being blunt but that is a really shit idea.
- Snarks are fast and intentionally difficult to shoot
- In multiplayer, having hundreds of the things squeaking and bouncing around waiting for someone try and shoot them would get annoying as Hell.
- Unnecessary strain on your system if there is hundreds of them running around at once.
- Snarks are fucking irritating.
