Tektite

The Tektite is a one-eyed spider enemy that has appeared in every Zelda game except The Wind Waker. It comes in several varieties including Red, Orange, Blue, and Golden Tektites. They are usually found in mountainous areas such as Death Mountain and Mount Crenel. Tektites attack by jumping at Link. Certain varieties also posses the ability to walk on water. The Tektite is considered a "normal enemy", considering it only takes one or two sword swipes to defeat (depending on which sword/upgrades you have). Projectile weapons such as slingshot seeds or arrows work as well. The Hookshot or Longshot is effective in stunning the Tektite and drawing it closer (Ocarina of Time), but not killing it. Being that Tektites have appeared in almost every Zelda game, it is important to note that their attack pattern has hardly changed at all since they were first introduced. Physically, Tektites have seen minor differences over very many games, but attack wise, they remain relatively same (head-butting and pouncing).

Red Tektite
The Red Tektite can be found mostly on land. They are opposite to Blue Tektites but always aim to use the same strategy in battle. They maneuver on ground rather cunningly, but a few slashes of the sword should easily kill these critters. They often frequent hotter areas such as Goron-inhabited mountains, however are not regarded to be one of the more heat-inviting species in these vicinities (in the Goron Mines in Twilight Princess they are situated amongst the more refreshing water-container mining compartment rooms).

Orange Tektite
The Orange Tektite appears in the Oracle of Seasons and Oracle of Ages. While the attributes of the orange tektite are identical to those of the red tektite it just a color alteration that makes them different. While some might be tempted to consider these creatures as actual red tektites, the color distinction becomes clear when comparing other red and orange enemies within Zelda titles.

Blue Tektite
The Blue Tektite is a variety of Tektite which can be found in several games in the The Legend of Zelda series. It will follow after Link, bouncing, until it reaches him and does relatively small amounts of damage. They can walk on water and can jump down areas of considerable heights, which makes areas like Lake Hylia and the Water Temple in Ocarina of Time perfect habitats for them. They are quite simple to kill; two blows with a regular sword or one shot from the Bow and Arrow will get rid of one in no time at all.

The Legend of Zelda
The debut Zelda title also marked the debut of this common Zelda enemy. The original instructions booklet describes this jumpy creature as being a "spidery thing". Tektites appear exclusively within the overworld of the game, and often times travel within groups of 4 or 5. There are tektites that appear to be blue and orange, however the tips and tactics expanded instruction manual refers to the colors as being blue and red. . The two types of tektites act nearly identical except that red tektites can jump further.

The Adventure of Link
The second Zelda title featured Tektites that are arguably more dangerous than in any title before or since. Much larger and more resilient than before, these Tektites shoot fireballs out of their single eyes and feature nearly impenetrable hides, requiring Link to cast the Fire Spell and then strike their single eye either directly or by shooting a fireball into it.

The Minish Cap
In The Minish Cap, the red tektites jump frequently whether they see Link or not. The Blue Tektites jump much more frequently than the normal tektites; they jump about three or four times in a row. The Golden Tektite appears only in The Minish Cap, looking like a normal Tektite, but much tougher and gold-colored. It will only appear as the result of a Kinstone Fusion. If Link defeats the beast, it will drop a large rupee.

Twilight Princess
In Twilight Princess, they are found mainly in the Lakebed Temple in certain rooms, and in one room in the Goron Mines, though later, they can be found in various parts of Hyrule. They are able to be killed with a few slashes of Link's sword.

Phantom Hourglass
In Phantom Hourglass, Tektites appear on Isle of Ember, they appear in two colors, blue and red (red are the strongest). They attack by aimlessly hopping around in a attempt hit Link. They require two hits to defeat.

Spirit Tracks
Tektites in Spirit Tracks mainly appear in caves in the overworld. They attempt to fall onto Link's train to do damage. Some tektites also appear along with the Rocktite.
