These are my uncle's golden balls! please make good use of them.
Uses the word kin no tama (金の玉), slang for testicles, to refer to the nugget. even though there is only one ball, the word in japanese doesn't distinguish between singular or plural so you're not able to tell. This line is said by an NPC in the games and was localized in english as "That's a NUGGET. I can't give you any nuggets of wisdom, so that'll have to do!"Thanks.I don't really understand, but I'll treasure it.
