A Blockhead's happiness bar shows the speed of the blockhead. It is calculated according to his hunger, environment, energy, and health bars. When its happiness bar lowers so does the speed of the Blockhead. By keeping its happiness bar at maximum a Blockhead will be able to travel faster, craft quicker, and mine faster. No matter what happens a Blockhead's happiness bar will not be higher than its health bar, so if all bars are at maximum except happiness, it might be a good idea to check to see if the health bar was overlooked.
In order to maintain your blockhead's happiness to the maximum, the following conditions must be met:
- The health bar must be at its maximum
- All bars except the health bars and the air bar must be kept at or above a certain level
