Walden Media will develop, finance and produce an animated film adaptation of “Platypus Police Squad,” Variety has learned.

The children’s series by Jarrett J. Krosoczka centers on two duck-billed detectives in Kalamazoo City tasked with busting illegal candy sales and tracking down political corruption. The books are published by Walden Pond Press, a collaboration between Harper Collins and Walden Media. Three installments have already hit shelves and a fourth sequel is in development.

The move comes as Walden has been busy unveiling a slate of films such as last month’s action adventure “Everest” and next summer’s “The B.F.G,” a Steven Spielberg-directed adaptation of the Roald Dahl children’s classic about a lovable giant. Walden is co-financing those films, but the studio has been ramping up its in-house production and development operations, as well.

The screenplay for “Platypus Police Squad” will be written by Jon Saunders and Ross Evans. Saunders is also on board to direct. Walden Media Vice President of Development & Production Naia Cucukov will oversee the project for the company. A distributor for the film has yet to be determined.

Krosoczka is an author and illustrator with more than 30 books to his name. His “Punk Farm” picture book and “Lunch Lady” series are both also currently in development with other studios.

He is represented by The Gotham Group and Rebecca Sherman at Writers House. Saunders is represented by Verve and Evans is represented by WME.
