In Kingdom Hearts, the Wishing Star can be found in a chest at Geppetto's House after Geppetto and Pinocchio escape from Monstro. In Kingdom Hearts: Chain of Memories, the Wishing Star is the signature Attack Card for Monstro.
The Wishing Star's overall appearance is similar to the cogs and gears in a clock. The teeth of the Keyblade is one gear attached to the main blade by a piece of wood. There is another small gear on the main blade. The handguard is comprised of four gears of various colors, and pieces of wood attached to pulleys with string connecting the pulley to the gear. The Keychain's token is the star that Geppetto wished upon in Pinocchio.
Also, the form Kairi's good luck charm takes after being altered by Naminé in Kingdom Hearts: Chain of Memories bears a slight resemblance to the Wishing Star's Keychain.
The names of the Wishing Star's leveled-up forms in Kingdom Hearts Re:coded are designed to invoke the image of a shooting star, with the trail growing with as the level increases. The name of the Keyblade itself may reference to the wishing star seen in the movie Pinocchio. It is the same star that Geppetto wishes upon when he desired to have Pinocchio become a real boy.
