Mattia has finally arrived, the lion's little brother! But where to put it? Mom Penguin says she won't always stand in her bed, she will soon grow. "Of course you can't stay in my room!" Leone says. And on my mother's knees there is no place for two. A baby is too small to stay on dad's shoulders, really too small so as not to get lost in the big embraces of the mother. And then between dad and mom there is only space for lion. "I really don't know where we could put it, this baby penguin ..." Lion insists. But at some point, he has a wonderful idea. "Oh, I found the place where we can hold Mattia!" He says. "Among my arms ... Look, they are perfect for a very small baby penguin!"
