Minjo

"Rarrrr! I'm a Minjo, arch enemy of the Jinjos!"

- Minjo

Minjos are the arch-enemies of the Jinjos and look identical to them, with the only difference being that they work for Gruntilda. First appearing in Witchyworld, Minjos will imitate Jinjos from a distance, waving their arms and calling for help, but will spring into action when Banjo and/or Kazooie approach, growling and chasing after them while giving off yellow sparks, meaning Banjo and Kazooie should be careful when collecting Jinjos, as they may really be Minjos in disguise. Because of their small size and high speed, they can be hard to avoid and even harder to attack, but a well-aimed Rat-a-tat Rap will dispatch them with a single hit, with rolling being completely ineffective. The player can also distinguish Minjos from Jinjos simply by firing eggs at them from a distance; if the eggs hit and damage the creature, then it is a Minjo. They can also be easily identified if they are a color that the player has already collected all the Jinjos for.

Minjos also appear in Banjo-Kazooie: Nuts and Bolts. Once a Jinjo is released from a prison, a Minjo must be found, carried and put into the empty cell, Banjo earns notes from Pikelet for doing so. Unlike in Banjo-Tooie, these Minjos do not look exactly like Jinjos. They wear tattered prison clothing and handcuffs, sporting a devious smile and red eyes. They are also all light purple. Minjos are easily discernible by the cackling noise which they make when Banjo is nearby, and are usually located nearby vacated prison cells.

Trivia

 * You can also tell which is a Minjo since Minjos are usually in wide open spaces, while Jinjos are found in places behind bars, hard to reach places, etc.
 * Some versions of Banjo-Tooie add sharp teeth to the Minjos (as well as their talk icon), making them easier to identify.
