How do you get a totodile egg in Pokemon HeartGold?

Answer 1

You'll need either a Totodile, Croconaw, or a Feraligatr. If you decide to breed it with a Ditto (which can be found on Route 34), it does not matter what gender Totodile, Croconaw, or Feraligatr are. But if you decide to not use Ditto, then Totodile, Croconaw, and Feraligatr will need to be female. (if you want your Totodile to learn a certain move that it only learns through breeding, then it must be female, while the father knows the move.) Some pokemon that Totodile, Croconaw, and Feraligatr can breed with are:

slowpoke

mareep

loudred

kangaskhan

poliwag

Marill

wooper

after you're set with your two pokemon, leave them in the day-care (route 34) for a while. (a pokemon can forget moves while in the day-care if left long enough). a totodile egg will hatch after a minimum of 5,355 steps have been taken.
