When Pikachu is left exhausted in battle, the gang meets a trainer who guides them to a secret, yet legendary lake that somehow serves to restore energy to the Electric Pokémon that live along its banks.

Ash, Misty and Brock stop by a lake where they meet with Team Rocket. As they're about to battle each other, a Slowpoke with a flag comes and sits on a rock fishing. This lady comes and says the Slowpoke is looking for "enlightment". She offers everyone to take to Slowpoke Temple to learn this. There's a giant gold statue of a Slowpoke. They go through tests, such as having to concentrate so hard they won't move or else they'll be hit by sticks(!). The next is cleaning the temple, which Ash and Team Rocket compete in. Jesse and James go off to steal the statue, and Meowth distracts Ash by fishing with him. The same Slowpoke is fishing much better than Ash and friends, because the pokemon know they won't be captured. The gold statue is stolen by Jesse and James, but Slowpoke evolves into Slowbro and defeats them. Ash and friends head off, while Team Rocket stay at the temple, this time to truthfully learn enlightment.
