Zol

Zol (ゾル, Zoru) is a large, gelatinous creature that appears exclusively in the two dimensional Zelda titles such as The Legend of Zelda, Link's Awakening, and Oracle of Ages and Oracle of Seasons. However, they will make their first 3D appearance in the upcoming Wii game Skyward Sword.

The Zol may have been the precursor to the ChuChus, seen in more recent Zelda games. Phantom Hourglass marked the first occasion in which both enemies appeared in the same game.

Characteristics
The Zol's primary habitat ranges from dungeons and caves in The Legend of Zelda and A Link to the Past, to the overworld in Link's Awakening and the Oracle series. This foe, though often associated with the Gel, is an entirely different creature, despite obvious physical similarities. While Zols do yield two Gels, respectively, when struck with a weapon, it is possible to defeat these creatures through the use of a more powerful weapon (such as the white Sword from The Legend of Zelda) as such so that the enemy bypasses the Gel stage altogether. As their most common incarnation facilitates the split into the Gel form upon attack, it could be said that these creatures carry twice the vitality and by extension, offensive power as their Gel counterparts. Interestingly, the Zol of A Link to the Past is the only incarnation not to experience a Gel phase when attacked, however, it is also the version in the most abundance, as it appears in three different colors across the Hyrule overworld: green, red, and yellow. Coloration of Zols is not limited to A Link to the Past though, as Link's Awakening also incorporates red and green Zols; the red Zol is the stronger of the two, and can divide into Gel if struck with a weak weapon (a strong one will simply defeat it), while the green version is much less powerful and does not divide into Gel upon attack.

Only the green Zols of Link's Awakening, and by extension, the Oracle series, can pop out of the ground in an ambush, attacking Link in a radically different way in comparison to the commonplace, bouncing strategy of other titles' incarnations. Speaking of unique attack strategies, the Zol of Phantom Hourglass can attack Link by latching on to him, instead of bumping into him, like usual.

Weaknesses
As Zols are often commonplace enemies, they can be defeated, or submitted into their Gel form with the most conventional of weaponry, including the Sword, Bomb, Boomerang, Arrows, and the like.
