Blob
The blob is a monster class that appears in NetHack, and is represented by the lowercase b glyph (b). Blobs are designated internally by the macro S_BLOD.[1]
The class contains the following monsters:[2]
Common traits
Blobs are neutral amoeboids: they are unbreathing and lack limbs, eyes or a head. Each blob is generally slower-moving than an unhasted and unburdened character, and they have a tendency to wander around while moving. Blobs have sleep resistance and poison resistance.
Generation
Randomly generated blobs are always created hostile except for the acid blob, which may generate as peaceful towards neutral characters.
History
The blob monster class first appears in NetHack 3.0.0, where the acid blob, quivering blob and gelatinous cube are moved to that monster class and given their current glyph.
Encyclopedia entry
These giant amoeboid creatures look like nothing more than puddles of slime, but they both live and move, feeding on metal or wood as well as the occasional dungeon explorer to supplement their diet.
But we were not on a station platform. We were on the track ahead as the nightmare, plastic column of fetid black iridescence oozed tightly onward through its fifteen-foot sinus, gathering unholy speed and driving before it a spiral, re-thickening cloud of the pallid abyss vapor. It was a terrible, indescribable thing vaster than any subway train -- a shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and unforming as pustules of greenish light all over the tunnel-filling front that bore down upon us, crushing the frantic penguins and slithering over the glistening floor that it and its kind had swept so evilly free of all litter.
