I have not played this game in a long time but I think I remember that jojora uses a wand
so use your hammer to hit it when she uses it and it will fly away and she will cry and go
to get it and not be in the battle for a couple turns and her friend (attack her if jojora
is not there because jojora will counterattack)the friend has a weakness to luigi's
thunder and mario's fire so when her hair color is pink use luigi's thunder then she will
say she thinks one of the brothers likes her and then when her hair is yellow attack with
mario's fire and sometimes she will wink at one of the brothers that means she will attack
the one she winks at and you have to hit a huge snowball she makes or jump on her hands if
she goes after you trying to kiss you and don't use mario's fire when her hair is pink or
luigi's thunder when it is yellow because it will heal you and when jojora returns just
attack her until she attacks and hit the wand away and then do it over again Hope This
Helps!

sorry when it says heal you I mean heal HER.

AND some people call jojora a him but it doesn't matter
