Grid bug

Grid bugs are one of the weakest monsters that appear in NetHack. They are unique in that they cannot move or attack diagonally, which naturally extends to their polyform. Some have proposed moving like a grid bug as an unofficial conduct.

One demonic malediction mentions polymorphing into a grid bug to give the player a "fighting chance".


Grid bugs are easily handled by all but the most unfortunate beginning characters - they usually deal no damage at all, unless they manage to zap you as well, and even then the damage is very small. This electric attack cannot break your rings and wands unless the grid bug manages to gain a level above zero.

As such, they are nothing to worry about once you pass experience level 2, and are best left as fodder for a pet you want to train, since they gain at least one maximum HP per kill. If you need to train up a weapon skill, grid bugs can also be useful as target practice.


You can't get there from here...
You attempted to move or attack diagonally while polymorphed into a grid bug.


The concept of grid bugs came from the 1982 Disney film Tron.

Encyclopedia entry

These electronically based creatures are not native to this
universe. They appear to come from a world whose laws of
motion are radically different from ours.
Tron looked to his mate and pilot. "I'm going to check on
the beam connection, Yori. You two can keep a watch out for
grid bugs." Tron paced forward along the slender catwalk
that still seemed awfully insubstantial to Flynn, though he
knew it to be amazingly sturdy. He gazed after Tron, asking
himself what in the world a grid bug was, and hoping that the
beam connection -- to which he'd given no thought whatsoever
until this moment -- was healthy and sound.
