Helio-grub

Helio-Grubs are small grub-like green insects that glow in dark caves. They can be picked up with the OmniWrench Millennium 12 and used a a sort of flash light by Ratchet in the dark Morrow Caverns of Planet Merdegraw. They can only be found in small pools in the caves. They can be used to explore dark places, but more importantly, to get rid of creatures that are frightened of light, like Thwogs.
