After you get the pokédex he will call you soon.Try riding with mister Brynie the guy with the boat!Hope that answers your question.
You have to complete all 202 Pokemon on the Hoenn Pokedex. When this is done, Professor Birch will call you on your Pokenav. Go to his lab and you can select Chicorita, then raise it.
You need to have Pokemon Emerald to do this. In Emerald, catch all 202 Pokemon. Professor Birch will call you to his lab on the Pokenav. Go there, and Birch will let you have one of the Johto Starter Pokemon. Choose Chikorita and raise it to a Bayleef (it will evolve at Level 16). Then raise Bayleef to Meganium (it will evolve at Level 32). Send Meganium to Pokemon Diamond via Pal Park. To get Meganium you must catch all 202 Pokemon in Pokemon Emerald. Professor Birch will call you on the Pokenav and tell you to come to his lab. Go there and Birch will let you choose one of the three Johto Starter Pokemon. Choose Chikorita and raise it to a Bayleef (it evolves at Level 16) and raise that Bayleef to a Meganium (it evolves at Level 32). Send Meganium to Pokemon Diamond via Pal Park. You cannot catch wild Chikorita in Pokemon Diamond without cheating using the action replay.
when you beat the elite four, prof birch will call you and you will be able to go there with the ferrier
Once you complete the hoenn pokedex which consists of 200 Pokemon you do, professor birch will call you and says that he has a special present for you. His present is one of the johto starter Pokemon, Totodile, Chickorita, or Cyndaquil. Also, in Pokemon Emerald version, you can get johto Pokemon at the battle frontier and in the safari zone, but only for emerald. nonononope, you can't get to kanto with emerald. try Pokemon gold,silver or crystal.if you really want to travel 2 regions in one game..
the only way to get cyndequil is to catch ALL 200 hoen Pokemon and get a call from the professor and he will give either a totodile, chikerita or a cyndiquil (1 only)
Basically, -just- and I use the term loosely, obtain all Pokemon obtainable in Emerald/ruby/sapphire, on such games, then choose a johto starter (Birch will call you) and trade. Only way, sorry.
Your supposed to fill the complete pokedex. hoenn and national
First, you have to complete the Battle Frontier COMPLETELY(Gold and Silver)!! Then, Proffesor Birch will call you and talk to you in his lab. Then, he will give you another starter of your choise(Torchic, Mudkip, or Treeko).
You can do bonus quests, such as go visit the Abandoned ship, catch all three Regi's Catch Rayquaza, Kyogre, Groudon, and complete your pokedex! ((P.S. if you catch every single Hoenn pokemon, Prof. Birch will call you on your pokenav and give yo a big reward!))
