Stinky Ghost

The Stinky Ghost is an enemy in EarthBound and Mother 3.

In EarthBound
The Stinky Ghosts in EarthBound can only be found in the sewers of Fourside, which are leading to the fifth Your Sanctuary. It is an enhanced version of the Smelly Ghost, where the only visual difference is the color that has gone from red to a nuance of green.

In Mother 3
The Stinky Ghosts in Mother 3 are only present in Osohe Castle and their overworld sprite only becomes visible when the player comes close to it. Other ghosts known as Friendly Ghosts also inhabit the castle, but in contrast to the Stinky Ghosts, they will not attack and instead assist Duster.

The Stinky Ghost in Mother 3 resembles the Zombie Possessor from EarthBound significantly more than its name-related counterpart.

Battle Memory description
"Some ghosts in Osohe Castle are understanding and kindhearted, but these ones are plain ol' mean."
