The Secret Saturdays is an American animated television series created by Canadian cartoonist Jay Stephens for Cartoon Network.

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.

The Saturdays are members of the Secret Scientists, a global organization with the goal of studying and safeguarding sciences considered too dangerous to be general public knowledge.

In the first season of the show, the Saturdays are also pitted against bounty hunter Leonidas Van Rook and his apprentice, who is later revealed to be Drew's long-lost brother Doyle Blackwell, who was separated from her after their parents died in an accident in the Himalayas.

The Saturdays also discover an ancient mirror which leads to a dimension made of antimatter, and encounter their evil counterparts, whom Zak dubs the "Mondays."

Meanwhile, the Secret Scientists have turned against the Saturdays, wishing to capture Zak and place him into cryogenic sleep to prevent him from becoming a serious threat.

They scooted across land, sea, and air in what Stephens called a Campercopter and their goal was to preserve the mystery of the Earth's strangest creatures before they were exposed by humans or destroyed by the cryptids' nemesis, Monsieur Dodo.

The art style of the show was influenced by the artwork of Alex Toth and 1960s Hanna-Barbera action cartoons, such as Jonny Quest and The Herculoids.

Michael Tavera created the music score for the show after finishing his work on Time Squad, ¡Mucha Lucha!, Lilo & Stitch: The Series, and Yin Yang Yo!.

One area of the program's website also held a "secret" document:[5] while most of the words on it were blackedout, the names of Drew and Doc (two of the main characters) were revealed.

Another site was linked to CryptidsAreReal.com: the page for an organization called Ten Hero Tusk (an anagram of "the Kur stone"), which states that its explorers are "D. Blackwell, B. Finster, and L. Van Rook", all of which are characters in the show.
