Lola absolutely, completely, totally refuses to smile for her school photograph—no way, not ever—until big brother Charlie hatches a top-secret tickly plan. With squeaky camels, invisible cheese, and the perfect timing of a sneeze, Lola finally unleashes the biggest grin just as the camera clicks. Lauren Child’s signature collage chaos and quirky sibling banter make this a giggle-out-loud favourite for ages 3–6.
