The Grenado was a primitive explosive. It was the Special Weapon of the Pirate. The grenado is a hollow ball of clay filled with black powder, with a fuse protruding through. To use this weapon, the fuse was lit and the grenado would be lobbed towards the target. In the close confines of a ship, it would be particularly devastating. In the show, a grenado exploded hanging on a rope between 3 dead pigs. 1 pig was covered in plate armor. The grenado released deadly shrapnel on its explosion, causing deadly wounds on all 3 pigs. Though the shrapnel could not penetrate the plate armor, it was the Pirate's second-most effective weapon, with 198 kills.
