so,,, the treasures the roos dig up

its seems that when you have certain coats you will get certain treasures like my koi find rice and bamboo,,

the highland finds the the short bread,,?

but ive been gettiung short bread for a while withour having an highland ,, until today when i got my first one

so,, could gettind short bread,, indicate that one of your roos has the highland coat trait hidden,, and if you are around and see which roo found the shortbread,,

could it possably be an indicator to keep that roo?

and if you see another roo finding shortbread,, an

indictaor to put thsoe two roos together?

so my koi found bamboo,, rice but not much so i dont have many roo with hidden koi trsts but i do get a lot of broken pipes and bananas but also have alot of winecoats and fawn,, etc
