The Weblum is a gigantic species of worm that surpasses even the massive size of the Galran command center. According to Coran, the Weblum is an integral part of keeping the universe function by feeding on dead planets, reconverting the quintessence remnants into the building blocks of new solar systems. Weblums are also a source of scaultrite. It first appeared in the episode The Belly of the Weblum.
The Weblum's outer skin appears to be made entirely out of rock but its organs are completely organic. It has two pairs of three eyes on either side of its head. Its natural defense is a venomous laser that vaporizes anything in its path, which causes the scaultrite gland in its third stomach to goop and create scaultrite.
It possesses three stomachs through which swarms of bacteria roughly half the size of a human head that break down the food with acid.
Being a non-sentient creature, the Weblum would attack any moving object in its line of sight.
