Corporal Pig

Frank is a Medium Pig that wear stone helmets for stronger defense. They are the third strongest pig variety in the game, and serve as the chief enemy in the first set of levels in each theme. They also serve as protectors to the King Pig. Helmet Pigs are very much alike to Mustache Pigs in game ways, not actual looks. They have bosses: Herr Helmet, Hovering Helmet, Hardhat Hidalgo, Billy the Pig, and Cave Explorer. Also, those bosses are achievements. The Helmet Pig first appears in Poached Eggs Theme 1-21

Trivia

 * Helmet Pig and Postman Pig are the only pigs that don't display their ears.
 * Along with the other Pigs, the design for Helmet Pigs have changed in the Angry Birds Chrome Beta, they have shinier helmets with buckles on them.
 * The Helmet Pig plush is the only Pig that is all beat up and in it's corpse.
 * The helmet the Helmet Pig is wearing resembles a nazi german helmet used during World War II.
 * In the Chrome version the Helmet Pig's helmet may be made of metal which may explain why the helmets are shiny and can be dented.
 * If you look inside the Helmet of the Helmet Pig plush, you'll see that he doesn't have any ears.
 * Many of Angry Birds fans request a Helmet Pig plush that is NOT beaten up to be available in stores.
 * In new animations, like Wreck the Halls and Ham 'O' Ween, the belts can be see wrapped around the Helmets of the Helmet Pigs
 * As shown in the Ham 'O' Ween and Wreck the Halls animations, the Helmet Pigs hold giant knives (the ones to spread butter with, not cutting/slicing things) and forks. It is possible that these giant pieces of silverware and kitchen utensils are weapons of choice for the Helmet Pigs in the animations.
 * In the Year of the Dragon animation, the Helmet of the Helmet Pig is different. It has a different shape, gold bearing at the bottom, no buckle, and a feather on top of the helmet, kinda resembling him as a Chinese Knight/Guard Pig or something.
 * The Helmet Pig also holds chopsticks in the Year of the Dragon animation. It's a possibility that it is a weapon of choice for the Helmet Pigs in China because the Helmet Pig used them to make the audience of Bad Piggies applause during the puppet show.
 * One the of Helmet Pigs appears as a teacher in the "Meet the Pink Bird" animation. He reveals in his plan written on his chalk board that after he gives the King Pig the eggs, the King Pig gives him a medal for succeeding his plan.

Strategy

 * Don't over estimate the power of the Helmet pig's helmet. Even though the helmet is stone, it is weak. The Red Bird can destroy him in just one hit.
 * Using a Blue Bird also works, but make sure you split it 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. Don't use ice. Ice is weak and will not work on helmet pigs.
