This mug portrays a green "Zombie Surfer" with surfboard and driving his Woody Wagon.

He is a zombified version of the original "Surf Gasser" design.

From Tiki Farm's website:

"'The Legend of Surf Gasser' by Derek Yaniger

From the very moment he was hatched, Surf Gasser was a Surf-Crazed Gearhead!

A single-minded Beach Bum Beast, who, in his crazed pursuit of surf, will shut down all gremmies who dare try to drop in on his wave! Hodads beware! Surf Gasser will shut you down!

Surf Gasser prays for surf every night and every day in the hope that Kaha Huna will send monster waves his way!

And when he's not makin’ with the Quasimodo bit, He's hiding out in his beach shack gassin' up his Woody Wagon for the next day's Surfari! If you happen to run into Surf Gasser on his mad race to the sea, DO NOT get in his way or you will surely fall victim to a surfer's stomp that's a guaranteed WIPE OUT!"

Now, he is the monster of the "monster waves" and you better beware his "surfer's chomp" as well as his "surfer's stomp"!
