A gelatinous cube is a fictional monster from the Dungeons & Dragons fantasy role-playing game. It is described as a ten-foot cube of transparent gelatinous ooze, which is able to absorb and digest organic matter.
The gelatinous cube is an invention of Gary Gygax, and first appeared in the Monster Manual (1977), rather than being lifted from outside sources and adapted to a roleplaying setting, as were many mythological monsters like the minotaur and dryad.
Being a cube that is a perfect ten feet on each side, it is specifically and perfectly "adapted" to its native environment, the standard, 10-foot (3.0 m) by 10-foot (3.0 m) dungeon corridors which were ubiquitous in the earliest Dungeons & Dragons modules.
The gelatinous cube appeared in first edition Advanced Dungeons & Dragons in the original Monster Manual (1977). The creature was further developed in Dragon #124 (August 1987). Published first edition Advanced Dungeons & Dragons adventures which included gelatinous cubes as adversaries that the player characters encounter included "The Ruins of Andril", published in Dragon #81.
Under the ooze entry, the gelatinous cube appears in the third edition Monster Manual (2000), the 3.5 revised Monster Manual (2003), the fourth edition Monster Manual (2008), the Monster Vault (2010), and the fifth edition Monster Manual (2014).
A gelatinous cube looks like a transparent ooze of mindless, gelatinous matter in the shape of a cube. It slides through dungeon corridors, absorbing everything in its path, digesting everything organic and secreting non-digestible matter in its wake. David M. Ewalt, in his book Of Dice and Men, describes the gelatinous cube as "a dungeon scavenger, a living mound of transparent jelly".
Tyler Linn of Cracked.com identified the gelatinous cube as one of "15 Idiotic Dungeons and Dragons Monsters" in 2009, stating: "Unless an encounter plays out exactly like the steamroller scene in Austin Powers, we fail to see how the Gelatinous Cube ever kills anybody who's not either glued to the floor or fast asleep. In fact, we're pretty sure the Dungeon Master's Guide reads: The first player to ask "Can't I just get out of the way?" automatically defeats the Gelatinous Cube."
Chris Sims of the on-line magazine Comics Alliance stated of the gelatinous cube that "there can be no question of what is the greatest monster" in D&D, calling the gelatinous cube "amazing".
