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. Luffy, Franky, Robin and Zoro forced him to show them around the castle, only for Zoro to go missing. Then, the zombie generals appeared, and Buhichuck ran off leaving Luffy, Franky and Robin to fight them. His shadow was stolen by Gecko Moria's "Shadow Asgard" technique in chapter 481.
