Bubble confidently walks right to the tent, securely holding his sleeping bag and pillow for his overnight tent adventure with his sister, uncertain Pearl, who awkwardly holds her gear as if it might fall on her feet. When night comes, she looks wide-eyed and uncertain where Bubble is the picture of calm manly courage, so at ease that he falls asleep even though three mice join them in the tent. He wakes up to welcome a cat, rabbits, dog, sheep, hen, and horse, but once the tent is full to bulging, everyone including no-longer nervous Pearl falls asleep to dream. Pearl’s trepidation doesn’t add to the story; instead, it mildly supports a body of literature that pictures girls as timid and afraid. The expressive, simple watercolor and black line drawings introduce and then expand this aspect taken from the text, but also add to the joy of outdoor adventure and the humor involved in a tent stuffed with children and animals. Kruusval’s (You’re Growing Up, Pontus!, 2001, etc.) skill in color and design heightens the effectiveness of the cumulative structure of the text with a grace to charm a young reader who may read one more book before going to sleep.
