This is an 18 card set.
Professors Crump and Vooshka head off to a caravan site where Roman remans have been found. Vooshka's English is not so good....does she really mean cramped or crumpet? Fred and Ernie are also heading to the camp to fish for some girls but when they meet Carol and Sandra they get a bigger bite than they want! And what is the link between Henry and Daphne! 
The story of each character is told on the back of each card.
