Jacob Blue

Jacob is the only member of the Umbrella Tree household capable of flight and sometimes enters the house by flying through open windows. He usually sleeps in his own bird house on the patio. Jacob sometimes invents things but they seldom work as he plans, resulting in a humorous outcome. Has a tendency to get things mixed up and saying "I knew that" whenever he finds out about something. Jacob is the tallest of the trio. As revealed in "How it all Began", Jacob was the first occupant in the apartment. Iggy and Gloria soon followed, and eventually Holly.[7] He was named after his twenty-times great-grandfather, Sir Jacob of Blue, said to have invented the catapult and defeated the evil Duke of Doublepeck, and married Lady Flyella.
