this character has three full lines and no impact on the plot whatsoever. she appears in around 60% of the fanart on pixiv. similarly, Tony, who has about four scenes in Earthbound, appears in close to 70%.
this is the Mother fandom. this is how it works. take a character, minor as can be, give them some memorable quirks, sweet harmony.
on a side note, after i experienced this little stalker shrine room i felt like i needed to take a bath
