Lantern Mouse

Lantern Mice are creatures found in the dark urban areas of the world, specifically Shaded Citadel. They are not aggressive, and in fact can be used to navigate through dark areas. They are extremely helpful due to their bio-luminescence, but tend to flee from you if they perceive you as a threat.

Appearance
Lantern Mice look like glowing hamsters with big eyes, two dots on each side of their body, and elastic tails they use to hang from the ceilings and scaffolding. They come in a variety of colors, including red, green, yellow, and blue.

Properties

 * Lantern Mice are bio-luminescent and glow with considerable strength, although they need to spend some effort to turn their light on.
 * They will run in fear at the sight of Slugcat, whether Slugcat is holding a spear or not.
 * They can be grabbed and dragged around as a portable light source, although they weigh the player down considerably, restricting movement.
 * They will repel small groups of spiders, but large groups will still attack them aggressively. Throwing a mouse into a group of spiders can help distract them for some time.
 * If you kill a Lantern Mouse while it's charging up, it will go back to its original color.

Trivia

 * Lantern Mice are one of the 10 backer-created creatures, specifically co-composer Lydia Esrig.
 * Lantern Mice are incapable of swimming in bodies of water and can do little else other than bob on the water's surface until some external force gets them to drift close enough to dry land for them to climb out.
 * Lantern mice are unafraid of Scavengers and will ignore them, the Scavengers likewise do not seem to acknowledge Lantern mice.
 * Lantern Mice have a 1/17 chance of facing the opposite way and a 1/8 chance of hanging their hands down when sleeping.
 * There is a 1/100 chance that any individual Lantern Mouse will have a completely random hue.
