Hyptothetically, if i bred a Noctowl with a Togekiss that would make a togepi (male) with extra sensory.
Then, I bred a Honchkrow with a Togekiss that would make a togepi (female) with nasty plot.
After that I bred the two togepi offspring, wouldnt this create a togepi with both egg moves? (i don't know anything about breeding so try to mind the ignorance)
No, because to get Extrasensory on a Togepi, you woud need to breed with a Male Togetic/Kiss or Noctowl with Extrasensory with the Female Togepi. Same with Nasty Plot, but with Honchkrow. Since neither Noctowl nor Honchkrow being able to learn both moves, it would be physically impossible to get both moves on one Togepi, unless you hack.
