Mothra Sectret Characters

I know that there are three secret characters for the Mothra. But The only one that I have seen anyone get is Godzilla. What about the other two? Also, does anyone have a on how to get Godzilla?

Only thing I've read was that Mokara turns into Godzilla eventually. I've read somewhere that Mothra gets you the twin fairies and Batra gets the egg looking thing.

What people say tends to be inconsistent. They say Mothra either leaves an egg and it becomes the twins or they turn into them. I pretty sure Mokara turns into Godzilla no egg involved. Both the Genjitchi and Mothra Tamas aren't very well documented and explored as the other Tama's are. Part of what makes them so much fun.
