New recruit Zeb the sheep joins the flock to help crack the greatest mystery of all! But, uhh...just what is the greatest mystery of all? Pondering that conundrum is what has kept the dearly departed General Inspectre tethered to Earth long after he should have moved on to the great super-spy base in the sky. Having a ghost haunting the halls of S.U.I.T. wouldn't be so bad...except he's possessed Monocle to serve as his Earthly form! Zeb--along with Cilantro, Bongo, Marsha, and cameos from everyone's favorite Gators--must decipher the series' biggest mystery EVER to free their pal and finish the Inspectre's unfinished business!
