The Secret Saturdays

Summary
The Secret Saturdays is an American animated television series created by Canadian cartoonist Jay Stephens for Cartoon Network. It debuted on October 3, 2008, in the United States. The series follows the adventures of the Saturdays, a family of cryptozoologists that work to keep the truth about cryptids from getting out, to protect both the human race and the creatures themselves.
