Forum:Kiabaman/Marshmallon

I have two questions. If I normal summon kaibaman onto the field can I activate his effect and tribute him to "Special Summon" the blue eyes onto the field the same turn I normal summon kaibaman? Since its a special summon I believe I can.

Also is Marshmallon an either or monster? If he is attacked face down my opponent takes 1000 dmg, is he destroyed if attacked face down, even though his effect says he cannot be destroyed by battle. I believe that to be the case. If that is correct it makes more sense to me if he had both a flip effect and an average effect labeled on him.
