This question is related to the question Can you breed Pokemon with Dream World abilities for their offspring to have the Dream World ability too?
So, let's create a scenario!
I obtained a Glaceon with the Dream World ability from the Eeveelution game event that passed before. (The one when you bounce a ball off a platform you control and break bricks, where at the end you receive one of the eeveelutions varying on how many balls you collected in the game).
If l breed this Glaceon, the offspring will be Eevee no matter what.
However, since there is only a chance of passing down abilities from their mother to the offspring, what will happen in this situation where Glaceon's offspring will not be a Glaceon, but an Eevee?
Will there be any chance of the Eevee having the Dream World ability, allowing me to evolve it into any other Eeveelution with a Dream World ability as well, or will the Dream World ability be exclusive for Glaceon only, and not be passed down to Eevee?
