Quoting from the GC3 description of the Snathi:
"These guys are E-V-I-L! ... Now, after billions of years hoarding their proverbial 'Nuts', the Snathi have metaphorically 'climbed out of their tree' and will 'gnaw the galaxy with their big squirrel-like teeth'... so to speak."
Now there are reports that they are here and gnawing on our critical infrastructure.
You have been warned.
