They are playing hide and seek. Pinky is the seeker and Spiky is the hider.
Pinky started to count and Spiky ran to find a perfect place/ spot to hide. Spiky saw big boxes that he thought would be a great spot to hide. He immediately fit his body inside the box.
Few moments later, Spiky felt someone is moving and carrying the box. The delivery man is picking up the boxes, where Spiky hid, because they were for sale.
Spiky is in danger now, let us hope that Pinky will be able to find him.
