On the way to Olivine City, Brock's Golbat begins to act strangely and flies to a archeological dig site. A girl named Tierra is there using ultrasonic waves to help dig up a special artifact, an ancient gold mask and scepter that once belonged to a queen. Together they have the power to control any Pokemon. Team Rocket hears this and plans to steal it.

At the end of a long day, our heroes search for a Pokémon Center in a small town near Olivine City. Unable to locate one they ask a local lady for directions. She explains the nearest Pokémon Center is ten miles away! Too exhausted to extend today's journey, the gang decides to set up camp in a local park. As he gets water from a nearby fountain, Brock notices a Nidorina approaching to take a drink. Running after Nidorina is her trainer, who trips and almost falls into the fountain. She is narrowly saved by Brock and immediately falls head over heals in love with him. Introducing herself as Temacu, she insists Brock and his friends stay with her at her father's house. They agree, but what will happy when a girl actually loves Brock and will do anything for him?
