Description Meet Bibsy Cross, the precocious, regular-pegular eight-year-old whose pickle-jar terrarium habitat gets a little out of control in the third installment of this charming chapter book series. Most things are easy-peasy, regular-pegular for Bibsy Cross. She loves her parents, her cat, her best friend, Natia. She loves school and the library. And she loves to lend a helping hand. For their class project, Bibsy and her group must create a self-sustaining pickle-jar terrarium. That means the plants and bugs will live in a harmonious balance. But when things go a little off-kilter in the pickle jar, will Bibsy's instinct to help out truly do good?
