Ai and his friends are excited to play in the snow! It might be chilly, but they know they have Grandpa's warm café waiting for them when they return. So when Aiko finds a big blue dinosaur shivering in the cold, they know they need to help him, even if they're scared. It's time for another Ai and Aiko adventure!Back at the café, the friends do everything they can think of to warm the dinosaur up. They give him hot chocolate, a hat and mittens, and every cosy thing they have. But the dinosaur keeps shivering and shivering! It's only when Ai comes face-to-face with his fear that he realises just what the dinosaur really needs. In this sweet and cosy winter story, a hug is the warmest thing of all.
