These stories start with Dilly's birthday treat to the Count Dracula Experience. Then Dilly gets a fright when a policeman turns up when Dilly has taken a box of chocolates from Mum's shopping. Dilly acts as a traffic siren with his supersonic scream, and is blamed for another dinosaur's behaviour.
