Flea Swarm

Creature 5 — animal, swarm

Pre-Remaster content. May include legacy alignment.

CrasherLANDanimalswarm

Flea swarms roil across city streets and rural hinterlands in a hissing, scraping scrabble, draining blood from any creatures unfortunate enough to cross their path. Fleas are little more than a nuisance in most circumstances, but can be lethal when they grow to monstrous proportions or gather in enormous swarms.
