The Chim Doll is a synthesized item in Atelier Meruru: The Apprentice of Arland. To unlock the recipe, Rorona must be a recruitable party member and your alchemy level must be above 20. These cute little dolls serve as mascots. Meruru must synthesize and deliver one to Arls National Mine during the Arls IV development quest. Totori also asks for one as part of one of her friendship events. If you do not give her the Chim doll, you will be unable to finish her ending.
