Great Skall is a giant, evil, undead, skeletal creature that looks like a cross between a willy whistle and a skel-monsta, and it is protected by a ring of monsta's while carrying a staff with a skull embedded into it, showing it can use magick. It also wears a necklace made of what appears to be human skulls around its neck, in a voodoo/hoodoo fashion. It is a very tough monster that serves as the final boss of Bubble Bobble Part 2 on the Nintendo Game Boy. It is responsible for taking people away and imprisoning them in its castle of death.
