List of key items in Mother

This is a list of key items in. This includes items which are relevant or compulsory to the game's plot.

Basement Key
The Basement Key or BasementKey (ちかしつのカギ Basement Key) is one of the earliest items acquired in the game. After the poltergeist leaves Ninten's house, Ninten will be instructed by his father to find something in the house's basement, which may assist him during his quest; his father has however forgotten where he put the key to the basement, making it inaccessible. The key is later revealed to be placed on the collar of the family's dog, outside of the house. After the dog gets checked and the key is obtained, Ninten can enter the basement, where he will find a Bread, a Plastic Bat and his Great-Grand Father's Diary.

Canary Chick
The Canary Chick or CanaryChick (カナリアのこども Canary Child) is located in the department store in Podunk, where it can be purchased in the pet store on the fifth floor. All the animals except for the canary chick have escaped, so the salesman will directly ask Ninten if he wants to buy it; if he replies yes, the seller will ask if he'd accept a price of $85. If Ninten then refuses to buy it, they will let him get it for free. The chick must be taken to the canary named Laura in Canary Village, as she is the mother of it, which will result in her getting so happy by the reunion that she will sing the second melody.

Great-Grand Father's Diary
The Great-Grandfather's Diary or GGF's Diary (そうそふのにっき Great-Grandfather's Diary) is the diary of George, Ninten's great-grandfather, and is located in the basement of Ninten's house. It can be obtained after Ninten has gotten the Basement Key from Mick's collar. Its purpose is left unspecified when first gotten, but it is later used to provide Ninten with the answers to what two pink rock-like objects telepathically ask him at different points of the game. The first rock is located in a cave east of Choucream Zoo, but is guarded by two policemen, and can't be accessed until Starman Jr. has been defeated. Using Telepathy on the rock will result in it asking him "who has lost his tail?", and if Ninten has the diary in his possession, he will manage to find a matching entry and say the corresponding answer out loud, being "the forgotten one of the ship that sails the cosmos", which leads to him mysteriously being teleported to Magicant. Another rock is located in the monkey-filled ruins of Yucca Desert, and will ask him the same question as the previous one. The sequence of words that triggers the teleportation to Magicant is however slightly different, being "the one who lost his tail", "the forgotten one" and "the ship that sails", in that specific order. This will as usual take him to Magicant, but when leaving through the Magicant Underground, he will be taken to a cave located northwest of Youngtown. Teleporting to Magicant the second time is however not compulsory to finish the game.

Ghost House Key
The Ghost House Key or Ghost Key (ゆうれいやしきのカギ Haunted Mansion Key) leads to the house of the Rosemarys in Spookane, which is infamous for the ghostly creatures inhabiting it. The key is recieved by the mother of the Rosemarys, who is located in the east of the town, after simply talking to her, as she believes that Ninten will be able to bring the house into control. The house itself can be found to the north of the inhabited part of the town, and is enterable after the key has been used on the front door.

Hat
The Hat (ぼうし Hat) is recieved by an old woman, who is present in the Reindeer Station. She will ask Ninten if he's heading for Snowman when spoken to, as she believes that the hat she's found is the property of a girl there. She will then give him the hat and exit the station. The hat is revealed to belong to Ana, as her name is sewn on it. The item is essential, as Ana only will join Ninten and Lloyd once it has been given to her. When she reclaims her hat, she can be seen wearing it on her overworld sprite.

Onyx Hook
The Onyx Hook (めのうのつりばり Agate Fish Hook) is first received after beating the The Fish in Magicant's Underground. It can be used anywhere to teleport straight to Magicant. However, it can't be used to leave Magicant, which forces Ninten to go through the underground tunnel again to leave Magicant before he or Ana learns Teleport. It is considered a very useful item, despite being optional. When Eve is in the party, this item can't be used. Whenever Ninten uses an XX Stone to teleport to Magicant, exiting the Magicant Underground will take him to a different XX stone.
