What Charlie Brown cartoon featured Snoopy as joe cool?

The comic strip is called, generically PEANUTS. Charlie Brown is the lead character but he is NEVER actually called ( Peanuts! as a nickname- there was a jazz musciain named (Peanuts) Hucko, a Saxophonist who sometimes appeared on Lawrence Welk"s program. Joe Cool as a surfer was introduced in the Peanuts strip some time in the seventies and reflected a California orientation, a la Beach Boys. somewhat oddly he wore dark glasses on the Board.
