Immedium's original four books inspired the popular animated television series that is broadcast on Disney Junior and Netflix and in more than 100 countries around the globe.

"Too many children's books talk down to kids, thinking that talking on their level equates to dropping IQ points. It's refreshing to read The Octonauts and the Frown Fish, a smart and entertaining kids book... it's fun and teaches a lesson to look past the exterior and appreciate what's inside. Comic book readers looking to get their kids into graphic storytelling early will want to seek out this one. Nice bed time story reading, this one is."
