there used to be a cartoon called "little blue" about an elephant when i was little (the theme tune is in my head, and said something about him getting his daddy's fountain pen and broke it in two (hence why he was blue, when the rest of them were grey))
"Little Blue, Little Blue,
Why do they call you little Blue?
Playing in his bath as some of us do,
He bit his mummy's fountain pen and broke it in two..."
