Zols are the basic RPG slime enemy of Zelda; If you hit them, they split into smaller versions of themselves. However, if you manage to kill them in one hit, they won't split and can drop loot, and by the time you have a better sword, their gimmick won't matter. Gels, which are what Zols split into, die in one hit, but don't drop anything and are faster than Zols, and even Zols themselves would die in one hit by the time you reached the second half of the game (unless you forgot to get a stronger sword), which is why I believe that Gels are better suited for later dungeons than Zols. Does this make sense?
