There were lots of them in this underground lake a long time ago...I see, this is a shuchuu.
Shuchuu is sake bug. The one that Suika used as an extract in her gourd.A shuchuu?It's so cute~I came here to catch it...No.Though as far as I can tell, it's still a baby...Your map led you straight to the shuchuu's habitat.I'm the one who fixed you, right!?I'll take it hooomeNoooo!But it's odd...I'm not giving iiit!...So give it.So it wasn't a treasure map...It seems like that is the only one left here.
