This is from my adaptation of  The House at Pooh Corner.

Christopher Robin (CR): A child. Innocent in the ways of the world but the master of the realm of his imagination. While CR is off-stage more often than not, he often provides solutions to the problems of the others. 

Winnie the Pooh (Pooh): A bear. Gentle, creative, gregarious, a little proud. Doesn't rely on intellect so much as intuition. Easily confused. Lives in the moment. Loves to sing and make up poetry on the spot.

Piglet: A small pig. Timid, unsure, anxious, and yet quite smart and determined when circumstances press. Pooh and Piglet are boon companions and have adventures together more often than separately.

Rabbit: A rabbit. A self-important busybody tending to rush about and try to do too many things at once. Generally a good sport and eager to please those who treat him well, but does have a bossy, manipulative streak.

Eeyore: A donkey. Irritable, melancholic, sarcastic, sometimes fatalistic and often demonstrating low self-esteem. When alone, Eeyore usually seems happy, and he is often found doing kind things for others. 

Tigger: A young tiger. The newest member of the company, he's excitable, inexperienced, very (almost too) friendly and desperately wants to be accepted and seen as a worldy adventurer. He tries way too hard.

Owl: An owl. He was wise and smart at one time but has aged into a parody of himself; imagine perhaps an old great uncle, once proud and strong, but now muddled. Pompous and wordy, not belligerent. 

Kanga: Parent kangaroo. A kind & tolerant caregiver, kindly watching over Roo and the other smaller animals. Adopts Tigger early on.

Roo: Young kangaroo. Roo loves to play and is full of joy and wonder.

Narrator: Introduces chapters and provides context.

On gender: the story is about a child and a bunch of stuffed animals. I’m confident that gender is irrelevant in this context. Go ahead and cast any role in any gender presentation, and change any gendering words in the script as you see fit.

If you cast a female Christopher Robin and want to portray her as female, feel free to alter the name to suit, perhaps choosing Christobel, Christophine, Christienne or Christiana.

In my staged reading this past August, we had a male Kanga; and female Roo, Rabbit and Piglet, and we'd have had a female CR, Eeyore and Owl also if my first choice actors had been available.
