Where do you get typhlosion in Pokemon Diamond and Pearl?

in order to get a Typhlosion on d/p, you would have to have a copy of any second generation game(gold/silver/crystal) and have traded your cyndaquil/any evolution of said cyndiquil you want to a copy of any third generation Pokemon(aka ruby/emerald/Sapphire) you can then go to palpark and transfer the cyndaquil/any evolution of said cyndiquil plus 6 other Pokemon to your d/p game to catch. why you can't just transfer from the second generation, I don't know, blame the programmers
