Jack is a young boy. He is bookish, careful and thoughtful, but he is NOT a nerd! Jack has tremendous curiosity about the world around him and loves to take notes about his observations. Jack tends to be very cautious in new situations, and his adventures in the tree house help him develop his confidence. He has a good (and protective) relationship with his younger sister, Annie, though her more impetuous nature often gets on his nerves. This is a big role and requires a strong singer and actor.

Jack’s younger sister and, in many ways, his opposite in terms of personality. She is a risk-taker who often follows her heart instead of her head. She sometimes teases Jack about his careful attitude toward life and encourages him to be more adventurous. She loves animals of any kind and has a very loving heart. Like Jack, this role requires strong singing and acting. When auditioning, you might mix and match your Jack and Annie hopefuls to see which ones have the best brother-sister chemistry. 

Morgan is an ageless librarian enchantress. By the end of the play, Jack 
and Annie learn that the Magic Tree House belongs to Morgan. Morgan magically turns herself into Polly so that she can try to help the kids on this adventure, so for most of the show, Morgan will be costumed as a parrot. Look for an actor who can move easily in a more elaborate costume for most of the show. Although she doesn’t speak or sing until the end, this large and important part requires one of your most mature female performers with both strong singing and acting skills.

The First Mate enjoys being in charge of his
 crew and must jumpstart the play with a commanding first line. He has solo singing lines and also helps to narrate the story, so cast an actor with a strong speaking and singing voice. This character can be played by a male or female actor. 

Captain Bones is the epitome of a fearsome, odious pirate. He enjoys being vile and mean. Look for an actor who isn’t afraid to really 
put himself out there – one who has both a physical and vocal swagger. Consider casting your strongest comic performer for this role – the absurd comedic tone of the play is highly dependent on Bones. If possible, it would be fun to cast an actor who is smaller in stature than his minions to highlight the comedy of his bullish ways. Although Bones does sing 
a solo part on “How Do You Do, I’m Captain Bones (Part 2),” those lines can be spoken, so if you have a kid who is a talented actor but a less-experienced singer, this role would be good for him. Captain Bones can be played by either a girl or a boy as long as the actor has a commanding stage presence and great comedic timing. 

Pinky, Stinky, Blinky and Slinky are henchmen for Captain Bones. Though these pirates are devoted to Bones, they are not nearly as clever or mean. These large speaking roles all require good comedic timing. These roles are good for kids who will relish being able to dress and talk like a pirate in front of their peers. Look for strong actors who can carry a tune, are good at focusing and taking direction and who are capable of working together as a team. Cast males, females or both. 

Jonah is a cabin boy who wants to help
 Jack and Annie escape from Bones. In stark contrast to the Pirates, he is kind, soft-spoken and tender-hearted. While being held captive, Jack and Annie teach Jonah how to read. Jonah’s solo parts in “Reading A Book” require a strong singer, and the role requires an actor capable of quiet subtlety, so if possible, cast one of your strong performers in this role. If you are short on boys, cast a girl to play a boy. 

Billy, Molly, Nathaniel, Wilhelmina, Peter and additional Pirates are the often funny and spirited Pirates under the command of Captain Bones. The named Pirates should be the strongest actors and singers of this group. If you don’t have enough boys to play Billy and Nathaniel, cast girls who would have fun playing a boy. Casting extra Pirates is a good way to round out the chorus and to utilize performers who are less experienced. 

Teeki the Seagull is a jubilant bird with 
a need to express her joy for life. She is the matriarch of the Island Creatures on this particular Caribbean island. Cast an actor 
who enjoys the spotlight and who is physically uninhibited – someone who has good vocal and movement skills and isn’t afraid to “get into the groove” of the “Tropical Island Song.” 

Pedro the Pelican is a prim and proper pelican. Although not a large role,
 Pedro has a few solo lines. It might be comedic to watch this rather rigid, self-conscious bird get lured into the groove of “The Tropical Island Song” until he or she is the most enthusiastic dancer of them all. Cast an actor who can play shy but who isn’t afraid to dance and let loose on stage. 

Stella the Starfish is a sweet, happy starfish who loves to dance. Stella has a few solo lines, so look for an actor who has a strong voice and can lead the other Starfish in a dance. 

The Island Creatures including Pelican 
#1, Pelican #2, Pelican #3, Lizard #1, Lizard #2, Lizard #3, Corey the Crab, Starfish Partner, Additional Crabs, Lobsters, Starfish and Jellyfish sing “The Tropical Island Song” and “Treasure.” Cast as many performers as your stage and program will allow. As long as you have a few strong performers representing each group of creatures, casting extra creatures is a great way to give additional children experience without the pressure of a large role. Feel 
free to assign character names to match the number of performers you cast. If needed, you can double-cast your more experienced Island Creatures as Pirates as well.
