Deeler

Deelers are forest-dwelling spider enemies that first appear in Zelda II: The Adventure of Link and later in all three Philips CD-i titles.

Zelda II: The Adventure of Link
Deelers first appear the forest areas of Western Hyrule in Zelda II: The Adventure of Link. They are featured in red and blue varieties. Deelers dangle in the trees by thin silk strands. At first, Deelers are at the top of the screen, and if Link walks by a Deeler, it moves down and attempts to hit him. If a red Deeler hits Link or moves close to the ground, it retreats back up into the trees. Unlike their red counterpart, blue Deelers drop directly onto the ground. After landing, the blue Deeler starts to jump around, attempting to hit Link. The blue ones do not retreat back up the trees. Blue Deelers pause a few seconds between each jump. Link can defeat both Deeler types by either striking them with his Magical Sword or by firing a sword beam at them. Both Deeler variants drop either a blue Magic Jar or a Treasure Bag when defeated.

Link: The Faces of Evil / Zelda: The Wand of Gamelon
In both Link: The Faces of Evil and Zelda: The Wand of Gamelon, Deelers appear as robust gray spiders that simply walk back-and-forth along the ground. In the former game, they appear in Militron and Harlequin Bazaar, which in the latter game, they appear in Dodomai Palace and Reesong Palace.

Zelda's Adventure
In Zelda's Adventure, Deelers appear in the Forest of Ogham and the Forest of Torian as simple, early-game enemies that scuttle along the ground randomly. They always face south and make a high-pitched croaking noise as they move. They only appear in blue, though a larger, stronger relative called the Squibber appears in the Forest of Canvula. Both more closely resemble than spiders.

Zelda Universe

 * "Deelers are poisonous spiders who inhabited the wooded areas of Hyrule. They commonly drop down on victims from thin silk strands because they are too impatient to wait in their webs. Deelers do not posses any of the magical power found in Gold Skulltulas."
