The species evolved as the only sizable lifeform on Oozesta II, a planet of boulder-strewn muddy plains. During their preindustrial period, Blobsters would spend their day wandering blind and deaf around these plains, until they bumped into a boulder. Cushioned from these impacts by their foamy fat, they would then use their impressive strength to lift these boulders and forage under them for beetles and grubs, shoving them into the puckered gullet at the top of the Blobster's body.
