Karcasa of the Desert

Okay, I think I know what to do now. I'll send you to Karcasa right now. The only problem is that he's...quite the salesman. You'll know what I mean. Do you want to go over to see him right now?

Alright, now head over to see Karcasa and ask him about Mushroom Castle. Again, thank you for helping me out with my research!

Hmmm... I don't know if I've told you this, but at your level, it might be easier to level-up around the desert. It's your choice, though...

Eh? Who are you? I don't think we've ever met.

Haven't you gone to see Karcasa at the desert yet?
