This rock-scissors-paper song is about representing different things with your hands, sort of shadow puppet style, by throwing different RSP combinations. For instance, a combination of scissors and rock can be combined to look like a snail. A combination of two papers can be a butterfly or a bird, or in the case of this strip, a pair of momiji (Japanese maple) leaves.
