The Royal Detective

When wannabe cow-superstar, Princess, is on location at the seaside as an extra in a new film about a kidnapped Prince, her bull-friend goes missing during the night. Has he been bullknapped? Is there such word?
Princess the cow has always dreamed of being a film star and The Royal Detective might just be her big chance, if only these stupid actors could understand what she was saying. But when her friend goes missing, should she stay on the set for her filming role, or should she take her newly appointed sergeant, Jackson the psychopathic ram, and go and do some proper 'detectiving' of her own? Were the sea-rats witnesses to crime and who is that suspicious man with the greasy hair? Come on Sergeant, there are villains at large.
