Meet a little hedgehog who is having a seriously bad day. He is grumpy, he is prickly, and he is absolutely convinced that nothing—not a silly noise, not a tickle, and certainly not a nap—will make him feel better. But he hasn't met you yet. You are invited to step into the story and see if you have what it takes to turn his frown upside down. You will be asked to hug, shake, and spin the book to see if a little bit of interactive love can break through the hedgehog's grumpy exterior. It is a funny and lighthearted way to explore those big, confusing feelings we all have sometimes. As you play along, you will discover that even the grumpiest moods can be lifted with a little patience and a lot of fun. Perfect for anyone who has ever felt a bit out of sorts, this story turns emotional regulation into a game. Join the hedgehog on his journey from grumpy to grateful, and see how much power your kindness really has.
