How do you get munchlax egg?

wrong you will get another snorlax but the right one is ( tested 20 times ) get a female snorlax with full incense and a male snorlax with leftovers they will make a munchlax egg. :) better

get a snorlax holding full incense and a ditto. put them both in day care and soon an egg will appear in there!

If you want a female munchlax, go to floaroma town and walk about 10455 steps (copied and pasted from bulbapedia) and hatch it.
