Bot

Bots, also known as Botos, are blue gelatinous blobs and common enemies that first appear in Zelda II: The Adventure of Link.

Zelda II: The Adventure of Link
Bots behave similarly to their red counterpart, Bits, except that Bots can jump. Both enemies are among the weakest ones that Link encounters during the game. They appear throughout the plains and caves of Western Hyrule and at Death Mountain. They also appear within palaces. When Link approaches a Bot, it attempts to jump at him. He can defeat a Bot by hitting it with the Magical Sword. It initially takes two hits to defeat a Bot, but if Link gains enough Experience for his first Attack upgrade, he can defeat one in a single hit. In caverns, some Bots fall from the ceiling in the shape of a drop, and upon landing on the ground, they form into their usual shape. If Link defeats a Bot, it may either drop a blue Magic Jar or a 50 EXP Treasure Bag. Link obtains 2 EXP by defeating a Bot.

In the Great Palace, Link fights several Boss Bots, which are a fusion of Bots. When Link attacks a Boss Bot, it splits apart into five Bots. They are stronger than normal Bots and require numerous hits from Link. If Link's Attack is at Level 8, he can defeat these Bots with two hits. Link receives 10 EXP for each of the stronger Bots that he defeats.

In the Water Town of Saria, Link can find a Bot sleeping in Bagu's house. This Bot is not an enemy, unlike the others. When Link talks to the Bot, it wakes up and reveals the location of the house's master, Bagu, who is at North of River. The Bot appears purple, due to the game's "blue" palette being used for villagers' purple clothes in towns.

Additionally, one of the Spell magic's purposes is transforming other enemies into Bots.

Link: The Faces of Evil and Zelda: The Wand of Gamelon
Bots appear as somewhat common enemies in both Link: The Faces of Evil and Zelda: The Wand of Gamelon, particularly the latter. They are extremely short, and as such hitting them with the sword is difficult. They do not jump in either game, instead just slowly moving to the side. The Faces of Evil also has slightly-larger purple Zols that appear earlier in the game and act roughly the same.

Zelda's Adventure
A variant of Bot known as the Tumblebot appears around the Vision Henge in Zelda's Adventure. They are more spherical, roll as they move, and are among the weakest enemies in the game.
