Ep 22. Pika and Goliath!

Ash and his friends reach the Canalave City and decide to explore the city and participate in the upcoming Canole City Pokémon Contest. As they walk through the city, they come across an abandoned building where they hear strange noises. Upon investigation, they discover a giant Steelix and a Pikachu trapped inside.

The Steelix is revealed to be the property of a local businessman named Goliath, who had been using it for his construction business. However, he had neglected it, causing the Steelix to become angry and rampaging through the city. Pikachu, who had been caught in the crossfire, had helped calm Steelix down and had ended up getting trapped with it.

Ash and his friends decide to help Pikachu and Steelix by freeing them from the abandoned building. However, they soon discover that Goliath has sent his men to capture Steelix and take it back to his construction site. Ash and his friends vow to protect Steelix and keep it safe from Goliath.

As they try to protect Steelix, they also have to deal with Goliath's men, who are using their Pokémon to capture Steelix. The group battles it out with Goliath's men and eventually comes out victorious, but not without a few close calls.

Throughout the episode, Pikachu bonds with Steelix, and the two form a close friendship. Pikachu even helps Steelix learn a few new moves that come in handy during the battles.

In the end, Goliath realizes the error of his ways and promises to take better care of Steelix in the future. Ash and his friends continue on their journey, leaving Canalave City behind but taking with them the memories of their encounter with Pikachu and Goliath.
