It appears that the supposedly late Dr. Shaggleford was, beyond being rich, an inventor in his own right, and his clueless young heir is now in possession of some very interesting nano technology.

The top secret nanotech formula has been mixed in with Scooby Snacks, which, when eaten, cause a variety of day-saving side effects.

Shaggy and Scooby-Doo have a mission: armed with an updated Mystery Machine, a loyal robot servant named Robi, their new riches, and the new and improved Scooby Snacks, they must stop the evil plans of Phineas Phibes and save the world.

In their spare time, Shaggy and Scooby are fans of the show Chefs of Steel, and the famous mystery solver Chad Chaddington.

DeLaurentis developed the concept in "three and half days" when he decided to do a show that solely focused on the titular characters and, with the help of veteran Matt Danner, began to add the elements that would eventually make up the series.

The character of Dr. Phibes was created because DeLaurentis was a fan of over-the-top villains and specifically chose Jeff Bennett to voice him during development.

The roles of Fred Jones, Daphne Blake and Velma Dinkley are downgraded, but they are not completely absent as they were in the Scooby-Doo and Scrappy-Doo shorts.

DeLaurentis revealed that the limited appearances were intentional as he wanted Shaggy and Scooby-Doo to develop as individuals and to provide a contrast as to how they have matured.
