The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed.
Heliogrubs were a small, grub-like insect species which glowed in the dark. Ratchet encountered these small creatures very early in the game on planet Veldin. Helio-Grubs only appeared during night-time.
Helio-Grubs were small and green, and they had large yellow eyes and tiny black pupils. They ahd a turqoise stripe on their faces, with a small mouth and sharp, but tiny, teeth. The creatures had four small legs, and they were extremely slow.
