The White Balloon (1995)

Razieh wants a fat goldfish for the Iranian New Years celebration instead of the skinny ones in her family's pond at home, because the fat fish looks like it's dancing when it swims. After many attempts she and her brother convince their mother to give them her last bit of money. Between their home and the fish store, Razieh loses the money. She finds it, but it is temptingly just out of her reach.
