This mug is shaped like a coconut resting on a base of skulls. The last design to be issued by Menehune Design group.

From website:

"You’re going to go cuckoo for Coco Skulls! These guys possess a fiendish charm with just a dash of daring. They’re a little bit creepy, a little bit cute, and a whole lotta groovy. Before you know it, you’ll be sipping in spooky style from these groovy ghoulies.

Natural coconut and skull coloring outside with a hearty dollop of drippy ghoulish purple on the inside. Limited edition of 50, numbered by the artist. Designed by Woodtiki for Menehune Design Group."

There is also an Artist Proof edition.
