Old dogs can learn new tricks -- if their name is Scooby-Doo, that is! Scooby and the gang are still at it fighting crime in the premiere episode of "Scooby-Doo! Mystery Incorporated." 

The gang's latest chapter of sleuthing has it all: haunted towns, radioactive materials and (of course) a sewer beast that cocoons its victims in frozen yogurt. (nutritious AND deadly.) 

And if you parents ever get nostalgic for your old "Facts of Life" days, Velma is once again voiced by Mindy "Natalie Green" Cohn!

"Scooby-Doo! Mystery Incorporated" premieres July 12 on the Cartoon Network.
