Meet Spriggy – the lovable little character created for Children's Hospital of Wisconsin to help kids learn how to stay safe.

He's got his own website, a mobile tour, local TV commercials, an app that turns safety lessons into a fun game and a series of webisodes in which he's chased by aliens, a giant octopus and a hungry dinosaur­ as kids narrate fun, imaginative ways to keep him out of harm's way.
