The Rockgrub is a passive fauna species. Despite superficially resembling an invertebrate, the PDA states that it is a possible relative of the Sand Shark.

Appearance

The Rockgrub is tiny in size. Its body is slim, round and segmented. It also has two swimming fins on either side and a larger flipper serving as the tail. The creature has five appendages on each side of its body, and a circular maw containing many small teeth.

The Rockgrub's most notable feature is the constant, bright bioluminescent green glow that its entire body emits to light up a small spherical area around itself.

Behavior

The Rockgrub swims rather quickly within its vicinity, seemingly scavenging whatever it could find. They are most visible in darker areas such as caves. Rockgrubs tend to traverse on tunnel walls or any surface in its vicinity.

Rockgrubs can be picked up, possibly for future use as bait for Rock Punchers to which they are prey.^{[Citation needed]}
