Young Horton explores the Jungle of Nool with his two best friends: going on daring adventures, helping their community, and learning how to stand up for what's fair.

Mabel centers on Callie, whose only friends are the plants and trees that surround her home. When her dad’s job moves the family to a sterile subdivision, she is utterly isolated—except for her best friend, a potted plant named Mabel. To Callie, Mabel is a peer, a fellow being, maybe overlooked or unseen, but still very much alive.
