Stylized dinosaurs play hide-and-seek in a counting rhyme that leads up to ten-osaurus rex, the “king of hide-and-seek.” He roars and stomps and chomps behind the big bush, while the other nine run and hide. After a big build up, it’s revealed that t-rex is a baby dinosaur, the tiniest one of the bunch. As he runs out to find the others, each one is hidden behind their corresponding numerals. The opening page of the story shows the dinosaurs as toys lying amongst other numbered toys, such as building blocks, a pull-toy, and a football, suggesting that the story itself was the result of a child playing.
