In just a few weeks, you'll be able to watch episodes of Viva Piñata TV Show on Saturday morning (in US and Canada).  Fox Television network's Saturday morning schedule was announced by 4Kids TV.  They've begun showing a commercial, caught here on YouTube. 

I got a chance to preview the first episode (I do believe in Chewnicorns!).  My kids (ages 4-10) are going to love the show.  And there was enough grown-up humor to make it fun for me to watch. 

From the press release:

Piñatas and Turtles and Monsters, oh my! In celebration of its 5th season on Fox, 4Kids TV - 4Kids Entertainment's four-hour Saturday morning programming block - is unleashing its most action-packed slate of original programming to date on affiliates nationwide. For the first time ever, 4Kids TV will add not one but four new series to its already successful lineup of popular returning shows. ...

Viva Piñata (premiering September 9): Produced in partnership with Microsoft and Rare Ltd., Viva Piñata is a CG-animated comedy series that goes behind-the-scenes to the fun-loving world of Piñatas. These treat-filled party animals live the sweet life on the lush Piñata Island. But what they like the best is to blast-off to parties around the world to bring joy and fun to kids of all ages. Join Fergy Fudgehog, Paulie Pretztail, Franklin Fizzlybear and Hudson Horstachio for a whole lotta laughs. Wherever they go, they're the life of the party! The fun continues with a Viva Piñata videogame available this Holiday from Microsoft.

Viva Piñata will also be featured on the new 4Kids TV On Demand network on Comcast ON DEMAND.  4Kids TV airs from 8:00 a.m. ET to noon ET on the Fox Broadcasting Network. Complementing the broadcast network is www.4Kids.tv which offers kids a 24/7 destination for video streaming of shows, games, promotions and much more.
