Fledge

Strawberry was the name of Frank the Cabby's horse, taken from Earth into the Wood between the Worlds accidentally, along with Jadis, Frank, Uncle Andrew, Polly Plummer, and Digory Kirke. From there, they all went into a pool which led to the newly created world of Narnia, where Aslan turned Strawberry into one of the first talking horses. Later on, Aslan again chose Strawberry for a special transformation, this time giving him wings and renaming him Fledge, the Father of all Flying Horses. It was the newly changed Fledge who flew Digory and Polly into the Western Wilds and eventually to the walled garden.
