Valkyrie's Ford Fiesta, also affectionately known as The Oompa-Loompa, was an orange Ford Fiesta given to Valkyrie Cain on her eighteenth birthday from her parents, Melissa and Desmond Edgley.
Desmond specifically requested the orange colour from the salesman to ensure it was as safe as possible, thinking it may glow in the dark (it doesn't). Valkyrie noted that it had a very nice dashboard, and a very nice smell. It was also very clean. She may be biased.
Skulduggery Pleasant kept spare cars hidden around Ireland, including an Orange Ford Fiesta. Unlike that one, however, Valkyrie adored her own.
