when u defeat the trainer red in heart gold (get to the top of mt. silver) go to pallet town and professor oak will give u a squirtle.
You need to pick Squirtle as your starter,And evolve him into Blastoise.other than that no idea.
Manaphy and Blastoise cannot breed. Manaphy can only breed with ditto or another Manaphy.
Pikachu Lapras Charizard Venasuar Blastoise Snorlax
Pikachu, Charizard, Blastoise, Venusaur, Snorlax, Lapras.
Red will have Pikachu,Venasaur,Charizard,Blastoise,Lapras,and Snorlax.
In Pokemon heartgold and soulsilver, the only way to get a blastoise is to go to professor oaks lab after you beat the gym leaders in kanto and you can choose one of the kanto starters check this site for more: serebii.net or: clover.top-forum.net zygloman

Unfortunately, you can't get a Blastoise in Heart Gold. But, in a certain point of your game, you will be given a Squirtle (Actually, depends on what you chose because there are two more choices--Charmander & Bulbasaur) by Professor Oak. Hope I helped :)
