A parent always worries that their child will catch cold in the winter weather if they don't wrap up warm. The Animal Alphabet series by Rosita Bird continues with the story of Charlie, the foolish Crocodile, who is so sure he can't possibly catch a cold that he won't wear his warm clothes. Lost in the snow, he is rescued by a volunteer from an animal shelter, who traces his mother and returns Charlie to his home. Charlie has indeed caught a cold, and learns to wrap up warm during cold weather in future! Charlie's mother is traced by means of Charlie's microchip, so this gentle warning also introduces the concept of animal rescue centres and the important work they do helping and rehoming animals, inspired by the animal shelter where the author's own beloved rescue dog was sourced.
