Hey, cooley. I've got a suggestion: Why don't you make a way from walby cave to the team knox's ship? Also, I got another Idea: Somewhere, you could make a special platform, where you can use Dig's outside of battle effect to go to Team Knox's Underground base (you could make one), where they have kidnapped Chikorita's. An elite of Team Knox then will say "Hey you! You want to free the Chikorita's?! Battle me first!" After defeating him, he'll say "Haha! I lied! Let's go Team Knox!" A Chikorita could be on the corner and it could be catchable, and then we would be able to catch all the Johto Starters :)
