As Ash continues his training, he, May, Max and Brock encounter Prof. Birch. Meanwhile a boy's Nincada was captured by Team Rocket and it digs a hole to a temple. There they encounter the commanders of the teams they encountered before: Team Magma's Harland and Team Aqua's Isabel. How will this clash of Aqua vs. Magma go down, and can Ash and co. help the boy save his Nincada?
The dub version of this episode mistakenly calls Tabitha and Shelly by different names; Harland and Isabel respectively. This was later rectified in later episodes.
In this episode, the Red and Blue orbs were referred to as the Rose Orb and the Indigo Orb respectively.
This is the only episode in which Shelly doesn't wear her trademark bandanna.
