The child in the foreground in the circle dress is reaching through a middle window in the box tower/dinosaur mountain. As she lets go of her dinosaur to drop to the bottom, the child in the orange shirt across the table from her reaches to the top hole in the box tower/dinosaur with her dinosaur. She then tries to drop her dinosaur through the top hole. The dinosaur gets caught momentarily so she has to readjust it so it will drop inside all the way to the bottom of the mountain. All the while the children make sounds they think a dinosaur would make if it fell into a hole.
