When does Shaggy & Scooby-Doo Get a Clue! return?

The show debuted on September 23, 2006, and ran for two 13-episode seasons during the Kids' WB Saturday morning block of The CW Television Network. It was the final animated series to involve Hanna-Barbera's co-founder Joseph Barbera before his death in 2006. This is the first Scooby-Doo series where Shaggy is not voiced by Casey Kasem.
