Blob monsters. Amorphous, often implacable due to their unique (lack of) anatomy, these creatures range from mindless eating machines to tricksy shapeshifters. Usually Nigh Invulnerable, and sometimes capable of Voluntary Shapeshifting. Often based on jellyfish, amoebas and similar invertebrates, this creature can be found throughout horror, fantasy and speculative fiction environments. Often acidic, it is usually defeated by being frozen, or by heroes who take advantage of its chemical composition with a stream of Techno Babble. If it has anything resembling a mouth, Phlegmings are assured.
