Apples
Through picking, you can find apples north of Frenzy Farm, in one of the two small orchards on the hill.
Map
Apples will be at your feet in great numbers. Each of them will instantly return 5 HP, up to a maximum of 100.
Mushrooms
They are found in the wet undergrowth around Slurpy Swamp and Weeping woods, southwest of the map. Mushrooms count as food for this challenge.
