Chameleon Birthday Postcard

This card is actually a little comic, in three pictures. In the first picture, you can see a birthday cake on the left hand side. It is a layered spnge cake, has pink frosting, and has a red birthday cake candle on top of it. The cake is standing on the brown floor, in front of a yellow background. There is nothing else in the picture. The second picture shows the exact same scene, only now, there is a pink line going from the cake to the right side of the picture. It runs parallel to the floor and leaves the frame on the right, so we cannot see what is at the other end of it. The last picture reveals what the pink line was. It is the same scene, only the picture zoomed out a little, so we can see that the pink line was in fact the tongue of a green chameleon, that is wearing a party hat, and is crouching in the bottom right corner of the card. The cake on the left is gone. The chameleon's tongue isn't visible anymore either, so that we as viewers guess that the chameleon swallowed it whole. Which explains its happy facial expression.
