The Cat in the Hat
is the essence of mischief, fun, and imagination. The Cat stirs things up, causes trouble, but always sets things right again, helping JoJo to discover the power of his own imagination as they create the story for the show together. Look for a physically adept actor (male or female) to play THE CAT, one who will be able to play many comic cameos and is comfortable improvising with an audience. The Cat does not need to be your strongest singer, but should still have good rhythm and timing.
JoJo is a "Thinker", a smart child with a wild imagination. He can be played as being a little bit awkward, a little bit of a loner, or simply a rambunctious kid whose Thinks get him into constant trouble. By the end of the show, he learns what it means to be a responsible member of his world, using the power and possibilities of his own Thinks. He should be one of your stronger singers.
Horton the Elephant is a gentle giant. Think of him as a big-hearted blue-collar guy who is steadfast, responsible and always tries to do the right thing for his friends. He is imaginative and receptive to the world around him. He is very unselfconscious.
