Rockin' Ghosts are enemies in Mother 3 that appear in the second floor of Osohe Castle, in a hall with mirrors. These enemies look like rocking toy horses being ridden by knight-like ghosts, which are only visible in the mirrors. They are first encountered by Duster in Chapter 2: Thief Adventure, and reappear up until Chapter 7. Oddly, the text of the Battle Memory appears to refer to the rocking horse rather than the ghost riding it. This could be because the Japanese name "Obake Mokuba" literally translates to "Ghost Rocking Horse."
