Packet of balls

We bought a different brand of nappies for our toddler. The packet had lots of pictures of a baby playing with a large purple ball all over it. Our toddler spotted the packet and was very agitated, and insisted we open the packet of balls for her to play with.
She was so insistent and didn't believe us that it was just nappies in the packet, so we had to open the packet and take some of the nappies out just to prove to her that it was not, in fact, a packet of balls.
