In the English prototype of Mother, some of the characters were redesigned, possibly to avoid resembling characters from Charles Schulz's Peanuts comic strip. One NPC character was given pigtails to reduce her resemblance to Marcy, Peppermint Patty's best friend, and the dust cloud was removed from an NPC that looked like "Pigpen". Ninten's mom was also given a different hairstyle, possibly because it resembled Sally Brown, Charlie Brown's sister. Ironically, Ninten's shirt was given a stripe, which made him look similar to Charlie Brown.
