""Whenever he was worried or whenever there was drama, Alex Allen's brain produced ... A living breathing Llama!" Alex Allen, like lots of children, sometimes worries about things-like dancing badly or getting an answer wrong in class. But unlike lots of children, every time he worries a real-life llama appears! And the more Alex worries, the bigger Llama grows ... which starts getting him into all sorts of trouble! Alex tries to hide from Llama, but it isn't until a teacher talks with Alex about his feelings, that Llama becomes quite small and lovable"-- Provided by publisher.
