Amusingly, I was only the other day reading Guards! Guards! by Pratchett.
In the book, there is a swamp dragon by the name of "Errol". The owner describes poor Errol as "a complete whittle".
Which comes back as Errol, who can't fly for the life of him, eats everything he can get his mouth on, breaks it down, and essentially creates an internal jet engine, complete with re-heat.
