The blob of gelatinous muck is a creature in the Spaceman Spiff universe that appeared in a single Sunday Strip.
Description[]
It was encountered on a "distant world" with a noxious atmosphere by Spiff, and manifested hostility by trying to eat him. As per usual, Spiff's weapon (here referred to as the "Blaster") proved useless against the otherworldly nemesis.
Notes[]
The blob was, in real life, lunch room tapioca.
