Penny the puppy has a toy pup of her own. Pup is all squashy and floppy and Penny chews and loves him to bits. With Pup for company, Penny doesn't need any other friends - not Henry the fat cat or Betsy the rabbit or Matt the fox cub. "Pup only wants me for a friend," Penny tells Henry. Then one day, Pup gets lost. How will Penny manage without Pup?
