To get unlimited Milk, try the following. First, equip the Touch Gloves and find your animal (cow, sheep, horse, whatever). Start brushing your animal, and allow the touch sequence to begin. Before the countdown gets down to begin, press any button to exit the sequence. Afterwards, you’ll want to quickly equip your Milker item with the touch screen (don’t cycle through your items to find it otherwise, or this won’t work). If you do this, your character will end up with Milk. This glitch can be repeated over and over again to get as much Milk as you want.
