Along with surfboards, and all kinds of surfing gear, the Surf Shack also sells do-it-yourself straw hats, Summer Luau style gear, and "unique ukuleles." A catalog (with Chuck as the cover model) is published every summer. 
Gaming tip: During the starting sequence, players can figure out the 3rd customer's order by examining the surfboards next to the shack. The first surfboard tells the size (3=Large, 2=Medium, 1=Small). The second surfboard tells the mixable (a purple snowboard with white dots means marshmallows). The third surfboard tells the syrup (a green surfboard with a white cross pattern means mint).
