Bot

are enemies in. They are common blue jelly-like slime monster which can be found all across Hyrule.

Characteristics
Unlike their red counterpart, the Bit, the Bot jumps to attack Link. They have a habit of jumping up at Link just as he is about to strike, which can make them dangerous in certain situations. While weak, they are found almost everywhere and can often knock Link into lava or water. Due to how common Bots are, and the fact that they reappear when Link returns to an area, they are a great source for Magic Jars. Defeating six Bots in a row will usually cause one to drop a Magic Jar. Using the Spell magic turns any regular foe into a Bot, reducing strong foes to weak slimes.

Dark blue Bots appear in the Palaces and are marginally stronger than the Overworld variety. They are just as common in the Dungeons as they are in the Overworld. Sometimes they appear as blue drips from statues at the top of pillars in Dungeons, similar to the dangerous red drops that appear. If these blue drops hit the ground, they will turn into a Bot. Link can wait near these statues and strike the Bots as they appear to obtain more Magic Jars. The Bots that appear in the Great Palace look the same, but are even stronger than they are in other Dungeons and offer more experience. Not only that, but the Boss Bot appears in this dungeon, which splits into five very strong Bots when attacked.

In the Water Town of Saria, Link can find a purple Bot sleeping in a house. If Link persists in talking to him, the Bot tells Link where Bagu, the owner of the house, can be found.

Trivia

 * Using a Spell to turn regular enemies into weaker foes is used in later games such as and  with the Quake magic and the Magic Powder turning enemies into Zols or Slimes.
 * The translation of the game can give the impression that the Bot in Saria is owned by Bagu, but he is simply referring to the "master of the house" according to the Japanese version, and is likely simply squatting in the empty building.
