Stegosaurus had 17 bony plates that were embedded in its back - the plates ran along the Stegosaurus' back and tail in two rows, and the plates alternated in alignment. The largest of these triangular plates was about 2.5 ft (76 cm) tall and just as long. Stegosaurus also had spikes at the end of its flexible tail (these are called thagomizers).
You can grab his head or on the bony plates. Sorry, we couldn't fit all 17 on him but he sure is fun to climb on.
