Stage 1-5[edit]
The enemy is a large monster. His attack involves pounding the ground, causing two zombies to rise from the earth.
Unlike the earlier opponents you encoutnered, he is immune to your flame attack. Instead, you need to use the flame on the smaller zombies, and throw the fireball at him to damage him. Once you hit him three times, he will die, releasing a large quantity of items.
If possible, try to get the item looking like a piece of meat for an extra life.
Stage 2-5[edit]
The enemy is a large skull on wheels. It's main attack is a charging ram, and there are only two safe zones that are possible.
The first safe zone is in the lower-left corner, but it is not feasable to damage the enemy in this location.
The second safe zone is on the right-side of the top-most platform. While it may seem that the upper portion of the skull may hit you, it's only damaging portion is below the top of the skull.
The skull will throw out enemies. When he does so, the enemies will eventually fall through the hole in the bottom of the screen and appear on the top platform. Flame them, and roll the resulting fireballs so that they hit the skull.
