Death
From The Blockheads Wiki
Death is when a blockhead dies. It was introduced in version 1.5. Death will occur if the death bar runs out completely, which can only occur if the health bar has depleted.
After death, a blockhead will start regenerating. A blockhead can be permanently killed at this point. Otherwise, the player can wait about 10 minutes for the blockhead to regenerate completely and teleport to the spawn portal. The wait can be rushed for 100 time crystals as well.
