“Pigs? You want to use the pigs?” Ivy glanced across the muddy field filled with winter-dead vegetation and the gray bloated bodies of dead hogs. At the far end of the field, through the bare tree branches, the wizard’s crooked tower was clearly visible. The tower looked solid, really solid, rooted down into the ground solid. But the Siegebreakers had promised the pig farmers that the tower would come down.

“Pigs explode?” she repeated to Mumchance, who had suggested that they pack the deceased hogs in the tower’s dungeon. Ivy trusted the 329-year-old dwarf, especially when it came to destruction, but this was the first time they’d ever used dead swine.

(Author's note again:  For those interested in the history of sappers, using hogs to undermine a wall is not exactly unknown in the real world. For how this plays out in a fantasy world, follow the link to the WOTC website)
