Go Go Ludicolo!

The gang decide to settle down for a picnic, and Ash takes the opportunity to introduce his newly-evolved Grovyle to his other Pokemon. While Taillow and Torkoal are happy to have him on the team, Corphish becomes worried that Ash will now favor Grovyle over the others given it's higher stage, especially when Grovyle manages to get fruit off a tree easily and fend off a Team Rocket attack. However the crisis is interrupted by a Ludicolo and it's bongo-playing trainer, who challenge Ash to a match. Ash decides that, since Corphish looks desperate for a battle, he should let it. However things don't go well and Corphish is easily beaten, which makes it feel worse and causes it runs off. While walking through the forest, Corphish finds the Ludicolo and it's trainer, but when Team Rocket attempt to capture the two, it's up to Corphish to save the day!
