The Osohe Ghosts are the inhabitants of Osohe Castle in Mother 3, and are a large group of friendly ghosts who only can be seen when a character is near them. While they can be found in many places in the castle, they are heavily concentrated in the ballroom where one plays Ragtime Osohe on the piano. One will also trade items (including the Rope Snake) for Rotten Eclairs. In Chapter 8, the Osohe ghosts can be found in the Empire Porky Building. They have been sealed into a bathroom, and do not seem particularly happy about this fact.
