Gelatinous cube
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. Creative origins. Oozes are relatively common antagonists in fantasy fiction; in addition to the oozes of "Dungeons & Dragons", examples include the monster from the film "The Blob", slime in "Dragon Quest", and flan in "Final Fantasy". These fictional oozes may have been inspired by microscopic organisms such as amoebae, which, like oozes, can consume organic matter by engulfing it (phagocytosis). The gelatinous  cube is an original invention of Gary Gygax, rather than being inspired by outside sources and adapted to the roleplaying setting, as were many mythological monsters such as the minotaur and dryad, all of which appeared in the 1974 Monsters & Treasure book of the original boxed set. Being a cube that is a perfect ten feet on each side, it is specifically and perfectly "adapted" to its native environment, the standard, by dungeon corridors which were ubiquitous in the earliest "Dungeons & Dragons" modules. Publication history. The gelatinous cube first appeared in the original "Dungeons & Dragons" "white box" set (1974), and  its first supplement, "Greyhawk" (1975). The gelatinous cube appeared in the "Dungeons & Dragons Basic Set" (1977, 1981, 1983). The gelatinous cube also appeared in the "Dungeons & Dragons Rules Cyclopedia" (1991). 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. The gelatinous cube appeared in second edition in "Monstrous Compendium Volume One" (1989), and the "Monstrous Manual  (1993) under the ooze/slime/jelly" heading. 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). Other publishers. The gelatinous cube is fully detailed in Paizo Publishing's book "Dungeon Denizens Revisited" (2009), on pages 16–21. Ecology. A gelatinous cube looks like a transparent ooze of mindless, gelatinous matter in the shape of a cube. The cube's transparency coupled with a dimly-lit dungeon gives it the element of surprise  to engulf unsuspecting beings, and only an alert adventurer will notice the cube. The cube slides through dungeon corridors, being able to mold its body to flow around objects and fit through narrow passages and then returning to its original shape once enough space is available. A cube will absorb everything in its path, with its acidic digestive juices dissolving 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", "The Ashgate Encyclopedia of Literary and  Cinematic Monsters" called it a "dungeon clean up crew", well adapted to this unique fictitious ecosystem. Reception. 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"." Although that line was humorous in intent, this option is not available in the game's standard 10-feet corridors, which the gelatinous cube is tailored to. Rob Bricken from io9 named the gelatinous cube as the 5th most memorable D&D monster. 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". "The Ashgate Encyclopedia of Literary and Cinematic Monsters" called the gelatinous cube one of the "iconic monsters" of the "D&D" game. Levi  R. Bryant calls the gelatinous cube "irksome and dangerous", "populating many a dungeon". In other media. Gelatinous cubes have appeared in the television series "Adventure Time" by Pendleton Ward. They also appear in several video games, including "NetHack", and "". A gelatinous cube appears in the 2020 Pixar Animation Studios film "Onward". The film's credits include a thanks to Wizards of the Coast for allowing them to use the Beholder and the gelatinous cube.
