Gelatinous cubes are monsters in ADOM. They are notable for being able to paralyze the PC if (s)he attacks them in melee range; which can often leave them open to attacks from more powerful creatures. Facing these in a lesser vault along with green slimes, and getting diseased from a slime whilst paralyzed, is certainly bad luck.
Gelatinous cubes are also notable for being able to dissolve (destroy) items on the ground that they walk on; which can make lesser vaults of jellies particularly unrewarding if these are allowed to destroy the treasures. This usually happens after at least a turn has passed since they step onto items rather than immediately, giving some time to quickly kill the cube and save the treasure. Gelatinous cubes also seem to have some more intelligence and form than other jellies — being vulnerable to mindcraft and occasionally leaving a corpse when slain.

Eating a gelatinous cube corpse paralyzes the PC and has approximately a 1/3 chance to grant paralyzation resistance. When paralyzation resistance is actually granted, you are paralyzed for a longer amount of time, and the message: "Your limbs are tingling in a strange fashion despite being paralyzed..." may be shown. Note that gelatinous cubes very rarely leave their corpses.
The first thing you'll note when a gelatinous cube is nearby is the total lack of any plant life or organic debris in the area. Gelatinous cubes are almost translucent with, sometimes, a slight green coloring. If you are lucky the cube will have some pieces of its last meal inside, so you'll be able to see it. So take a close look at those floating skulls!
