The Injector Monster is a strange six-legged creature found within the Prime Kindergarten.
Description
It is a reptilian-like creature with six legs. While most of its body is covered in scales, its back has an ember red mane. Its tail mirrors that of a Beaver, and the head long and narrow like a gharial, ending in a beak. It has one large conical eye.
It has the ability to scale up vertical walls much like a Gecko, and is capable of using its narrow beak like a jackhammer to dig deep tunnels into the ground. It's also revealed to "inject" its eggs into the ground with a similar method. It is also one of the few animals that eats Gemstones.
History
Season 7
The monster appears by Tiger's Eye soon after Bismuth and Lapis Lazuli split up, and tried to attack her, chasing her throughout the Prime Kindergarten. It only stopped its chase after landing on a Gem Injector, which collapsed under its weight, forcing it to retreat. It reappears shortly afterwards in the control room underground, where it already laid a clutch of eggs, and injected them into the ground before confronting the Gems again. In this assault it was knocked unconscious by Bismuth, who says to leave it alone as it's not a Gem, and therefore not their target.
It is presumed the creature left the Prime Kindergarten after this, as later appearances of the Prime Kindergarten have the creature relatively absent.
