Gelatinous Cube
The gelatinous cube is a large and slow moving species of slime native to most temperate dungeon regions.
They are prolific omnivores able to obtain nutrients from nearly any object they manage to suspended within their gelatinous flesh.
They reproduce through bisection often as a defense mechanism from being sliced by a sharp weapon. It's believed that all gelatinous cubes derive from a single ancestor colloquially known as the source cube.[1]
A group of slimes (including gelatinous cubes) is referred to as a smack.[citation needed]
