Buhichuck

Buhichuck (ブヒチャック, Buhichakku) is the boss of the "surprise zombies", in the dining room. At first glance he looks like an ordinary taxidermied pig's head mounted on the wall, but he can come to life and wield a pair of swords mounted below him as throwing weapons using concealed hands. According to him, there are more surprise zombies hidden in every room of Doctor Hogback's mansion. After defeating the Surprise Zombies of the living room, Luffy, Franky, Robin and Zoro forced Buhichuck to show them around the castle, not knowing that members of their crew were being picked off one by one for the zombie army. But instead of helping, the pig mount merely lead the team to a room under the controlled by an armored platoon of General Zombies. His shadow was stolen by Gecko Moria's "Shadow Asgard" technique in chapter 481.
