Hunger Bar
Hunger is one of a Blockhead's primary attributes, and is referenced by its Hunger Bar.
Display
A Blockhead's hunger bar is included in its character status window (See #3 in the provided image.), which is displayed when its character status icon is tapped while it is selected. The bar is also provided in a pop-up window above the active Blockhead when an edible item has just been selected from its inventory.
As with other attribute bars, a hunger bar changes color from right to left as it decreases, the reverse as it increases. The darker (or red) color is how much of the bar is empty.
Decreasing
If its hunger bar reaches zero, a Blockhead will start losing health.
The hunger bar should only decrease if the Blockhead is performing energetic actions like mining or crafting. However, it depletes at a slower rate than the energy bar. The only way to stop the hunger bar from declining is to meditate and, of course, wear the Sunrise Hat Of Fullness.
Restoring Hunger
The only way to restore hunger is to eat any of a variety of foods.
Seeds and worms provide very small amounts of health.
Most fruit provide the same amount of health, around 20% (one fifth) of a Blockhead's total health.
Meat (dodo or fish) restores more health than fruit. Raw meat provides less than cooked meat.
