Mario Kart Question?

someone told me at school tht if you get triple star on every grand prix you unlock another rob64 tht has its stats full on everything is this true

no, you get a special award known as having too much timemonty_4256

yup. it shows 3 stars over you in battle (or 1 or 2 if that's all you've done). none of it is worth the effort cuz no one who sees it online will care at all
