Once you get far enough in the game you will see the "Wizard's Outhouse" in the Wizards backyard wich is to the left of the Wizard there's a Kangamoo each time you kill it it drops a key this works over and over. unless they plan on patching this it is still a new game. Wizard's Outhouse is just out of the Haunted Forest.
