The penguins are hopeful and excited by life and are holding on firmly to their 'security' fishes because things can sometimes be a little bit scary... They would like someone to love and look after them!
I don't give tension for this pattern as it is largely unimportant. The difference in size between the adult and baby is due to the difference in thickness of yarn and needles. If you select a needle size slightly smaller than recommended on the ball-bank this will give you a nice tight fabric and the stuffing should not show between the stitches.
