Meet Felipe Femur. He’s a skeleton with lot of heart and a lot of love to give. Like most skeletons, Felipe Femur tends to stay hidden away. In his closet home he solves puzzles, builds forts, and has lots of fun on his own. However, there’s an awful feeling growing in his heart—a feeling of loneliness. On his quest to overcome this sadness, Felipe Femur meets up with his quirky monster friends: a toothless werewolf, a not-so-wicked witch, and a sun-loving vampire. His friends, though, have problems of their own. Using his brains, can Felipe solve their problems?
