Giggi are very low in the food chain while their still young. Giggi feed on the blood of other large species in order to survive but are preyed upon by some smaller predators. In the Tundra, they are hunted by Baggi packs. However, when a Giggi fully matures into a Gigginox, the tables are turned, and the hunters soon become the hunted.
When born Giggi are approximately 153.6cm. While small, Giggi can produce their own poison but not as effectively as Gigginox. From this they need to feed on the blood of other monsters not just to feed themselves but to also make their own poison. . When they make it to a certain size, they will cocoon themselves by using a thread from their mouth to make a cocoon. These cocoons can often be seen in the caves of the Tundra.
Giggi aren't very aggressive though are quite gluttonous. Once they see a potential prey item, they'll chase it down and attempt to attach themselves to the creature.
