Story
In the Kingdom Hearts series, he chronicles the adventures of Sora, Donald, and Goofy in his journal.

 * "Sora has taken a feline form in this world, but he seems to have two left feet...four left paws? Whatever." - Jiminy's Journal (Lion Sora article)

Origin
In "Pinocchio" Jiminy served as the main character's conscience. The Blue Fairy, who brought Pinocchio the puppet to life, gave Jiminy the task of guiding him and helping him to determine right from wrong.
