Pokemon Johto Journeys - Team Green (Vol. 45)
It's time for Chikorita, Sunflora and a Hoppip-impersonating Oddish to grow out of old habits and mature.  Fortunately, they have Brock, Ash, and Nurse Joy to help them.  Even Team Rocket gives an accidental assist as their plots predictably backfire - Team Rocket's blasting off again!
