Inkling

An Inkling (記憶) is a key item that appears in Kingdom Hearts coded. The sixteen Inklings, which appear as glowing white sparks, are scattered across Wonderland due to a bug. They are lost memories of specific subjects, and must be reunited with their owners, however, there is no way to tell who an Inkling belongs to, so Sora must guess by selecting the most appropriate Inkling to fill in the gaps in another person's memories.

Kingdom Hearts coded
Just as Data-Sora arrived in the next world, a girl appeared, being chased by Heartless and seeking help. After Data-Sora defeats the Heartless, he asks the girl for her name but she can't remember a thing. Then Cheshire cat appears, telling Data-Sora that everyone in the world lost their memories because the place has been "buggy". Data-Sora tells himself to find a Keyhole quickly when suddenly the girl responds that she saw a large Keyhole before, but can't quite remember where it is. Cheshire Cat then tells Data-Sora to restore her memories by finding Inklings before he disappears. Data-Sora then finds an Inkling, and use it to make the girl remember her name, Alice. Even though she remembers her name, she still can't recall where she saw the Keyhole. Cheshire Cat appears again and tells Data-Sora to look for more Inklings, and to be careful since not only Alice's Inklings are scattered across the world, but everyone else's too.

When Data-Sora asked the White Rabbit if he knew something about Alice, he said that he only remembers that he glanced at his watch and knew he was late to the trial. After telling this, the White Rabbit ran away and left another Inkling behind for Sora.

When Data-Sora approaches a card soldier, he tells Data-Sora that he made a big mistake: he planted white roses instead of red ones and gives Sora an Inkling as a reward for helping him. The soldier then asks Sora if he knows where he can find some paint, but Sora leaves without answering the soldier's question.

After Data-Sora retrieves the rest of her lost memories, Alice explains that she saw the White Rabbit and followed it down a peculiar hole. She then asked the Cheshire Cat how to get home. He suggested that Alice should visit the castle of the Queen of Hearts, and when she was trying to ask the Queen how to get home, she saw the Keyhole in the Queen's court. Then the card soldiers took her captive and were going to put her on trial, but she managed to run away before they could begin. She then started to chase the White Rabbit again and stumbled upon a strange tea party along the way. The tea party was hosted by the March Hare and the Mad Hatter to celebrate an unbirthday. She then met a Doorknob who refused to wake from his nap. After telling this, Alice gives Data-Sora a Cure +1 chip to thank him for his help.

There are also several Inklings that serve only as decoys: Heartless, Cookie, Red Roses, and Looking-Glass.
