HENRY A pteranodon that Jack and Annie encounter upon first arriving. Annie names him Henry and believes he is magic.
IGUANODONS The cool kids of the dinosaur lot. They have spikes for thumbs and are not afraid to brag about it.
JACK 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. Range: A3-D5
JOAN The most stressed out of all the Anatosaurus Mothers. Range: A3-C5
LARRY The nerdiest of the Triceratops and is a little henpecked by Terri, but he isn't afraid to speak his mind. Range: A3-D5
NATTY The ultimate mother hen and takes great pride in protecting the baby Anatosaurus eggs. Range: A3-C5
OTTO The oldest oak tree in the forest, a mild-mannered grandfatherly or grandmotherly type and a natural storyteller. Range: C4-E5
PANOPLOSAURUS Tank-like dinosaurs who take a lot of pride in all of their unique characteristics.

RED PINES/ HEMLOCKS Groups of trees who narrate the story for the opening and closing of the show.
SAPLINGS Young, spirited and curious Trees, eager to hear about the mysterious tree house that appears in their Woods.
STUMP A grumpy tree stump, who, in direct contrast to Otto, is impatient and ill-tempered. Range: C4-E5
SUSAN A sassy Anatosaurus Mom who is more intrigued by Jack and Annie's presence than afraid of them. Range: A3-C5
TERRI The most domineering of the Triceratops, but her bossy comments toward Larry should serve as comic relief and not be perceived as bullying. Range: A3-F5
TOTO Susan's pestering child. She (or he) is as sassy as her mother and a bit of an imp. Range: D4-A4
T-REX A fierce, meat-eating dinosaur that Jack and Annie encounter right before getting back to the tree house.
TROODON The "brains" of the dinosaur lot but are not braggarts.
