Gelatinous cubes

Creatures theme

Large (enough to block a hallway completely) animated cubes of gelatin like substance with animal-like intelligence, commonly found in "dungeons" where they primarily serve as automated janitors, collecting and melting any trash and vermin.


The first video game about Gelatinous cubes was released in 1985.

Interplay and Atari has published most of these games

Although gelatinous cube itself originates from Dungeons & Dragons, the concept itself is likely taken from H.P. Lovecraft's Cthulhu Mythos, specifically from Shoggoths which are similarly amoeboid (though not cubic) and originally worked as janitors and construction automatons for the Elder Things.
