Shelldon is a regular boy shell who, along with his family, has recently settled into Shell Land. A little shy and reserved, Shelldon does his best to stay out of trouble. And yet, despite his best efforts, trouble usually finds him. Matters aren't helped by the hare brained schemes of his best friends Herman, who's obsessed with "alien" (human) artifacts and "paranormal" events. Fortunately there is a voice of reason in the trio on form of Connie, an uptown girl who is covering up her privileged background by working at the Charming Clam Inn. Even though events often spiral out of control they come through in the end, while meeting a host of quirky characters along the way.
