Vulture Grub

Vulture Grubs are small, worm-like creatures usually found in tunnels and caves close to the surface. They can be eaten when dead, or used to summon s.

Appearance
Vulture Grubs have small, beige bodies, which turn gloomy when dead. Their grey heads are rectangular, and feature two bits on each side, which protrude out towards the body at an angle, alongside a darker spot in the middle, that blinks yellow, green or red while the grub is attempting to summon a Vulture.

Utility

Abilities & Behavior
Vulture Grubs don't do much on their own, often staying almost completely stationary, only making slight erratic movements.

Summoning Vultures
When thrown, Vulture Grubs emit a colored laser upwards. The laser starts out yellow, turning a different color after ~3 seconds to signify whether it has successfully summoned a Vulture or not.

If the laser has a clear shot at the sky within a region where Vultures naturally spawn, the laser turns green and a is called down. This may seem counter-productive to the Slugcat's survival, but a well-placed Vulture can cause pandemonium amongst a group of smaller predators, such as Lizards.

If the laser is blocked by a surface, emitted in an area without any natural Vulture spawns, or emitted in a region where all Vultures are dead, the laser turns red instead, and the Vulture Grub emits a beeping sound. No Vultures will appear.

If the laser is blocked by a surface outside, the grub may attempt to angle its body in a way that still allows it to summon a Vulture. While Vultures normally ignore Vulture Grubs, summoned Vultures always kill the grub that has summoned them if there isn't any other visible prey in the room.
