Three cards fill in one at a time: a dog turns see-through to show the skeleton inside it, a beetle and a spider share a card for a shell on the outside as their legs are counted (six and eight), and a worm in the garden has no bones and no shell, just a soft body that bends. Each card is labelled with an arrow to the body part, and the video ends with the recap that animals can have bones inside, a shell outside, or neither.
