Stinky Ghosts are enemies in Mother 3 and EarthBound, although they appear differently in both games. They are found in the Fourside Sewers in EarthBound, where they can drop Large Pizzas, and chiefly in Mother 3's Osohe Castle, where they can drop Rotten Eclairs.
Stinky Ghosts are formidable undead spirits that use standard attacks, inflict status ailments, and call for their cohorts. They are invisible at first, and, once approached, flicker into view and begin chasing their enemy. They may also pop out of some gifts and exhale their stinky breath, thus causing the Nausea status ailment. They are weak to Fire, Crying, and Duster's abilities. Their battle theme is More Dangerous Guys. They cannot be fought after the Pigmask Army appears, and their only other appearance is in Chapter 7 in the secret path near Aeolia's house. Their sprites bear a strong resemblance to the Zombie Possessor from EarthBound.
Their battle sound is Battle Sound 42 which is used exclusively by them and falls under Code Numbers 885 for regular attack, 886 for Smaaaash! and 887 for Miss.
