Zipacna is the first son of Seven Macaw and Chimalmat. Like his father, he believes that he's extremely important. He outsmarts the Four Hundred Boys when they try to kill him by burying him in a deep hole, and when they're too drunk to fight back, Zipacna brings their hut down on them and kills them all. Hunahpu and Xbalanque take revenge by starving Zipacna for two days, and then setting a trap for him by placing a fake crab under an overhang at the foot of a mountain. When Zipacna wiggles into the small space to get the crab, the mountain rests on his chest and he turns to stone.
