Strategy

 * One shouldn't over estimate the power of the Helmet pig's helmet. Even though the helmet is stone, it is weak. Red can defeat a Helmet pig in just one hit.
 * Using a Blue Bird also works, but one should make sure to split the bird before making contact.
 * Any bird can destroy the Helmet pig.
 * Wood that falls on him can kill him, but it requires more wood. Stone structures that fall on him can kill him instantly. One block that shouldn't be used is ice. Ice is weak and will not work on helmet pigs.
