Bokkus is a character created by Pat Wilson and drawn on the bass drumhead of the drum set that appeared in the garage photo on the inside of the Blue Album.In 1992-1993 the band had a Marvel Comics try-out book, where you finish the comic book.
Pat originally drew the "Bokkus" character on the backside of a drum head while recording the Blue Album at Electric Lady Studios, where it hung on the studio wall as decoration. Later, when he decided to use the head, he traced Bokkus onto the outside of the head, only to discover that the hole cut to accommodate microphones is right where Bokkus' pipe was, so the pipe is squashed below the hole. This led to people thinking Bokkus is blowing a big bubble out of his pipe.
After some touring the head was cut out and saved by Karl Koch. He then used the original head to trace a copy on paper which was used to recreate several new Bokkus heads for use on the Memories Tour.
