It's still unconfirmed, but the Punchbot seems to show up in The Robo-Wastes and in the Desert of secrets biome, but has two different appearances. It will attack on sight and can be a challenge for the unprepaired adventurer with a bad weapon. During the attack, it will open the front lid of its body and fire a mitten at the player. When destroyed, it drops Cubits, which can be used for Crafting. There is also a chance, it drops Weapons, emblems or gems.
