The Big Pile of Puke, known in Japan as Huge Barfy Slime, is an enemy that appears in EarthBound. It appears in the swamps of the Deep Darkness. It appears as a brown version of Master Belch, and even shares its overworld sprite with him.
In addition to the standard bash attack, the Big Pile of Puke can exhale tear-inducing stinky gas, and will also spit out mucus to paralyze a character. Instead of a nausea-inducing move, it can call for an Even Slimier Little Pile to fight alongside it. The Big Pile of Puke is weakest against PSI Freeze.
