Team Rocket manages to convince the Onix king who rules over a forest community of Rock-type Pokémon that Ash and friends have come to capture every last one of his subjects. Ash and friends, who were simply making their way to the Battle Arena, are thus surprised and confused when hordes of Geodude and Graveler suddenly attack them without provocation. Our heroes learn soon enough of Team Rocket’s part in their misfortune, but as they struggle to convince the Onix king that their intentions are good, Team Rocket begins capturing the Rock-type Pokémon for themselves.
