|Attack||Shooting out fiery fireballs|
Lava appears as a fiery orange liquid. Due to it being very hot, the lava constantly bubbles.
Lava causes instant death upon touching it, and shatters the chain between both angry heads. It may at some parts of some levels fire out lava fireballs that can damage the Knuckleheads. If an enemy is killed and its remains plummets into the lava, a sound of it falling into the lava is heard.
On some levels, lava will rise and the player will have to quickly make it to the top. Metal does not melt in Lava, even though is is often connected to it. Lava is found at the bottom of every level.
