Description from the USA back cover:
Go ahead... Hurl your head. It's OK... You've got another one. Use it to squelch pop-eyed super-slugs - and lots of other ghouls, goblins and creepy creations. You're Chuck D. Head. And you're beheaded for a bone-chilling adventure.
Boing off a pole. Leap across collapsing log bridges. Bop atop a roving eyeball. Then punch a skull head for extra propulsion. Or start a psychedelic earthquake in Dr. Frank N. Stein's lab.
Ghastly creatures prowl Eyeland's body parts. Totem poles bury you alive. Horned beasts lash their tongues. Finally, meet Max D. Cap. And remember: if he spooks you... it's all in your head.
