The Tale of Custard the Dragon is a poem for children written by Ogden Nash.
[4] In 1959, it inspired Leonard Lipton to write a poem that evolved into the song "Puff, the Magic Dragon".
The poem opens with the introduction of Belinda and her company of pets: Ink (the kitten), Blink (the mouse), Mustard (the dog) and Custard (the cowardly dragon).
His inmates take it for granted that he is a coward and makes him the butt of ridicule, calling him Percival.
Panic-stricken, everyone flees except Custard, who chases the pirate and devours him - proving himself the bravest of all.
