Crocs Inc and its subsidiary Jibbitz have signed a licensing agreement with Warner Bros Consumer Products that will allow them to feature the company's cartoon characters on their plastic clogs and shoe charms.

The new Crocs footwear designs will feature characters including Bugs Bunny, Tweety, The Flintstones, The Jetsons and Scooby-Doo.

Jibbitz shoe charms will be available in early summer with other Crocs products to follow in 2007.

"Crocs and Jibbitz boast an incredible global following amongst children and adults alike," said Karen McTier, executive vice president of domestic licensing and worldwide marketing for Warner Bros Consumer Products.

"This type of universal appeal is a natural partnership for our portfolio of properties."

Last month Crocs and Jibbitz signed a deal to produce merchandise based on DC Comics' characters Batman and Superman.
