First go to to the hunter, then go and click on standard or express (express is just faster) and click on the doughnut icon.

Now just wait a while until there is an alert saying "hunter caught pinata" and go to the hunter. Go to the last icon at the very right and buy the doughnut.

Now place the doughnut in your garden and guide your pretztail to your doughnut.

Your pretztail should attack and destroy the doughnut and eat the candy.

Now wait a couple seconds to minutes and your pretztail should turn into a blue mallowolf(not sour version).
