My daughter requested an improvised story about a King (a boy King), a Knight (a boy Knight), a horse (gender unspecified), and a Princess (a girl Princess).
(She specifies desired character genders because she knows Mom will make all Kings and Knights female unless otherwise directed.)
Once upon a time, there was a knight named Tim, and a king named Bruce. There was also a princess, named Miranda. They all lived together in a castle.
Toddler: And there was a bridge! [arms extended drawbridge-fashion] And a dark, dark forest, full of scary animals! [hands around eyes, like … a raccoon? I guess?]
That is correct! Have you been to this castle? There was a bridge, and a dark forest, and many scary animals.
