Surprises are in store this Fall, when the famous Warner Bros. amphibian (and spokesfrog for The WB Television Network), Michigan J. Frog, gets into the act when he makes a special guest appearance in an all-new mystery.

In the vein of Abbott & Costello, Lucy & Desi and Martin & Lewis, the series finds Sylvester, the always mischievous and often daring feline, teamed with an oh-so-endearing and cunning yellow bird named Tweety. And, of course, there's Granny, Tweety Bird's loyal elderly caretaker, who possesses a strange knack for detective work.

In each episode, investigative sleuth Granny (and all of her pets including Hector the Bulldog) are propelled to exotic locales around the world scoping out the latest criminals and uncovering each and every mystery that comes their way. Though natural enemies, the cat and canary must coexist to survive the perils of every challenging criminal case. But even that reality is not enough to keep Sylvester's natural instinct in check -- to devour Tweety whole. Sylvester's lifelong dream is to suck up to the person who feeds him -- Granny -- in hopes of sucking up a feathery bite-size morsel. As Sylvester once said, "I gotta have a bird! I'm weak, but I don't care! I can't help it! After all, I am a pussy cat!" While, on the other hand, Tweety's lifelong goal is to keep Granny happy and to do this he must solve Granny's difficult cases by ferreting out the most crucial clues. Of course, this is not easy when there's a prowling, stalking, fast-talking feline after you every minute of every day. And, it doesn't make it easy on Sylvester when his best con-artistry is foiled by Tweety's unruffled assuredness. (Tweety, by far, out-cons the best cons!)

Granny, Sylvester and Tweety on these adventurous outings is a burly bulldog-of-few-words named Hector whose ambition in life is to protect Granny at all times and make that smark-alek cat look stupid. Hector's brute strength and supposed canine cunning serve as one of Sylvester's greatest challenges.

But, when "Sufferin' Succotach!" is heard, the focus is on mystery and you can be sure that Granny and her menagerie are in the midst of one. Their cases vary. Classic Warner Bros. characters such as Yosemite Sam and Elmer Fudd serve as villainous luminaries making cameo appearances in some episodes where Granny tries to unleash their evil ways.

The group also attempts to unravel cases involving several of Granny's formidable adversaries. There is Moo Goo Guy Pan, an evil mastermind and former suitor of Granny's, who is also in his golden years and constantly attempting to thwart Granny in order to illegally acquire the world's riches for his own private collection. And, the team uncovers the criminal acts committed by Madame Pamplemousse, a crime novelist resentful of Granny's puzzle-solving success in the wake of her own failure.

Yes, this globetrotting foursome create chaos everywhere they go, but together they find the stolen Blarney Stone amid Ireland's lush greenery, outpace Spain's annual bull run in Pamplona and dodge ninjas in the glitz of Tokyo's Ginza district. Sylvester, Tweety, Granny and Hector provide unrelenting comedy as they encounter mystery and feline hunger in exotic lands around the world in each hilarious half-hour episode.

Joe Alaskey ("Steven Spielberg Presents Tiny Toon Adventures," "Who Framed Roger Rabbit") takes over the roles of both Sylvester and Tweety originally performed by voice-over legend Mel Blanc. Voice-over matriarch June Foray, the original voice of Granny, once again portrays the warm-hearted grandmother conjuring up memories of first recording the character in 1954 (Foray's other credits include "The Rocky and Bullwinkle Show" and "Smurfs"). Voicing the various villains are Jim Cummings ("Road Rovers," "Taz-Mania," "Steven Spielberg Presents Tiny Toon Adventures"), Jeff Bennett ("Steven Spielberg Presents Animaniacs,""Road Rovers"), Frank Welker ("Road Rovers," "Aladdin") and many others.

"The Sylvester & Tweety Mysteries" is produced and animated by Warner Bros. Animation, under the creative supervision of producers Tom Minton and Tim Walker, for Kids' WB!, The WB Television Network's children's programming service.
