When you said Red and Blue confirmed Marowak can have children, you’re forgetting the Kangaskhan theory that states inserting the marowak sprite and using the name marowak was a mistake; It was meant to be a ghost Kangaskhan. In Gold and Silver the pokemon tower and safari zone were removed and moved Kangaskhan and cubone together into the rock tunnel. Theory confirmed?
Ah, so your wild speculation is confirmed by someone else’s wild speculation?
Good, good. Carry on.
