Hahaha! that would be messed up too. He could however save it for later, wait for the appropriate time, and then throw it at ganodorf.
Then say
Link: "Ha! You thought I was gonna finish you off with some enchanted Light Arrows, NO, my friend, NO! Those are way to good for you my friend...so I decided to kill you with a normal, everyday-looking, flying rock!"
Well about the rock case and Walmart...I hope the kid didn't throw the rock at his mom or someone else.
I dunno if my mom told me she bought a Nintendo DS FOR ME, and I open the box and I see this...rock.
That very same rock is about to get HURLED at something or someone, than I'll pick up and take it back to the store of course.
