Dialogue

Marcellin Dialogue

There are many inventions of the Mad Scientist Marni to be found here,
but I'm mainly interested in these fellas right here.
These MOD Oogs
seem very interested in the many power cores I picked up nearby.

Marcellin Dialogue (Alt)

They seem very interested in the many power cores I picked up nearby.
Do you want a power core, too?

Marcellin Completion

I'll give you a power core.
Just a moment.
Hmm? Where'd they all go? I guess I used them all, except this one.
It's okay. I'm a girl of my word. Here you go.
Oh, before you go, I need to give something of a warning about these cores!
