When Larry and Kate discover a bag of catnip in Sierra's room they fear the worst -- that their teenage daughter has become a ""nip-head."" Taking the advice of the community drug counselor, they decide to confront Sierra but only cause her to run away. Meanwhile, in their quest to experience the ""ah"" they observed in a recent 7-Eleven TV commercial, Siegfried and Roy venture to the local convenience store to claim the ultimate prize -- ""The Big Gulp.""
In the quest to create a panda-breeding program, Siegfried and Roy import one of the few remaining male pandas to the secret garden for an intimate rendezvous with the community's romantically challenged female panda Foo-Lin. However, when Larry and Kate play matchmaker in order to speed up nature, they end up disrupting the complex process of panda-mating.
Settling into the fame of his new position as lead lion, Larry looks forward to his debut in the show until Siegfried and Roy proclaim to Matt Lauer during their appearance on the Today Show that they will unveil the greatest magic trick the world has ever seen with their new star. Panicked over the pressure, Larry turns to the crafty veteran performer -- Sarmoti -- to help prepare him. However, when the trick backfired during practice, a concerned Seigfreid and Roy turn to their proven veteran white tiger Blake to save the day much to the disappointment of Larry and Sarmoti.
