- "The Pitbull Slug, which you'll encounter in Deep Darkness, is as tenacious as its name-sake. They're hard to see in the murky darkness, too."
- — EarthBound Player's Guide
The Pit Bull Slug is an enemy in EarthBound, appearing in groups of four or six in the Deep Darkness area. It appears as a pink-colored Attack Slug. While they cannot concentrate, they can bash a character, use a vacuum attack, and use Hypnosis α. While they are extremely weak to PSI Fire, PSI Freeze, Paralysis, and Brainshock, they have full immunity against Hypnosis themselves.
