Marill can learn Present through breeding. However, both Azumarill's page and the Present page say that Azumarill can't. Since Marill can, then Azumarill must be able to as well, since there is no such thing as an Azumarill egg (without hacking).
I'm not sure why you would want an Azumarill with Present, but if you did, then you could breed it.
