If you shoot to the desert from the cannon, then go straight towards a monolith looking object. Three of the shadow beasts will appear and just defeat them for a portal.
okay, thank you....
hey, one more question... About giving 1000 ruppees away (i dont know how to spell it ... jejee), one bunch is for the man in the entrace of Hyrule Town and another bunch is for Malo to rebuild the bridge, right???
1000 rupees is for the bridge repair and then after that they ask for 2000 to open a shop in the hyrule castle town (which i think is how you get the price of the magic armor to be something you can afford but im not sure)
