The Tale of Custard the Dragon by Ogden Nash
Belinda lived in a little white house,
With a little black kitten and a little gray mouse,
And a little yellow dog and a little red wagon,
And a realio, trulio, little pet dragon.Now the name of the little black kitten was Ink,
And the little gray mouse, she called hum Blink,
And the little yellow dog was sharp as Mustard,
But the dragon was a coward, and she called him Custard.
